@UlrikeFischer The uppercase multiscript thing is fixed now. Sadly ConTeXt feature normalization does not seem to allow case-sensitive features, so table names are consistently mapped to lowercase now.

Chief Squirrel: everyone, I suspect someone among us is an infiltrator
Owl: hoo

@MarcelKrüger I saw the commit yesterday. Imho case insensitive is ok as long it is consequently done. Can the ISO tags be case insensitive too? I would find it more logical to use Beng instead of being.
@MarcelKrüger thanks. I think it will make the documentation clearer if I can use different notation for ISO and script tags. I will work on it in the afternoon. Regarding the AAT-ligatures. Could this happen for kerning too? I got a question by mail why a helvetica clone doesn't use kernings in lualatex but hadn't time yet to look more closely.
@UlrikeFischer well I had one the other day that pushed me off the 5-0 cycle so I made sure I rep capped that day, conversely just before I got 444444 I had a lucky downvote so I didn't answer any more questions that day :-)
@yo' the other day I spent an embarrassingly long time tracking down a bug in xurl and finally reporting a bug upstream and picked up at most a couple of votes, if I need to reach rep cap, I follow egreg's advice and just answer a few % at end of line questions. Voting patterns are weird, but fairly predictable...
@DavidCarlisle hm perhaps the comment should read "only redefine \@setsize if not under 2e", the following comment about 2.09 packages would then make more sense.
@UlrikeFischer Yes I wondered if that's what Robin meant except that then there is no code anywhere that scales parskip or footins in 2e as far as I can see. If you use say parskip package then \doublespace, baselineskip increases but parskip doesn't which doesn't match the documentation at the top, but I dare not change it probably thousands of thesis files using such a setting
@yo' no the classes are still under AMS control but it is on their radar (came up in an email thread with them the other day). I guess unlike other bug fixes they may actually distribute a public version with that since they maintain msc2020 and will presumably be telling authors to use it... If in doubt blame @barbarabeeton (retiring isn't a reason to avoid blame)
@UlrikeFischer the comments in that package are quite funny to read these days all about worrying about differences between tex2 and tex3 and between 2.09 and 2e.
@yo' I just checked: the information I have that they are planning on adding msc2020 support was on an email just to me and Barbara so not anything you can really quote but it was from a reliable source at the AMS.
@yo' -- I have learned from a reliable source that the AMS document classes are being worked on. Indeed, if they don't get an updated version out, there will be serious complaints from authors. However, the report didn't say whether the public update will meet the TeX Live 2020 cutoff. (Regardless of @DavidCarlisle's contention, not my problem.)
@yo' -- The necessary change for msc2020 is really trivial. The last public update put in only the msc2010 addition. So real fixes haven't been made for more than ten years. (I complained officially, but apparently to no avail. Changes are allowed to be made by only one person, and other projects have been deemed "more important".)
@UlrikeFischer Yes, for pure AAT fonts, all font features including kerning and ligatures will be ignored in LuaLaTeX. But I think this should only affect the Helvetica version shipped on Mac OS, I don't think that any other variant would rely purely on AAT.
I would be grateful if you could check my last comment https://tex.stackexchange.com/questions/525428/arara-how-to-conditionally-compile-the-document-if-changes-took-place-to-any-fi/525606?noredirect=1#comment1329745_525606 on your answer.
