@ilian I apologize for having use such "drastic" idiom but I still do find the question whether WRI employees do get a vote for closing bug-related questions valid in principle. To be clear, I greatly appreciate your effort and having you around does make M.SE more valuable.

@Kuba @halirutan @ C.E. @Nasser I know the rules for SE and have seen the bug-related-tag-warnings. :) But coming from economics and business, I would say: If such a public place to track bugs and "regressions" were not according to SE's rules then there should be another place for it as having such a thing should clearly benefit all sides.

In seeing a bug tag and a Case-reference here, I will not report the issue on my own since I know it has been reported already. This will save time for me and WRI at the same time. Also this open discussion and voting to WRI is valuable as it shows user interest - without additional cost.

While bug-tags can be painful and may not always be related with "anything we can do immediately" (e.g. "need to contact WRI" in the close vote) it most of the time is of interest to the community here (at least with Nasser's post it was imo) and there are sometimes deeper issues: Something has obviously changed that prevented integration rules to work as usual - maybe this relates to other functionality. Now, we will never know...

Last sentence: Think about it this way, Maple and MatLab have never gotten an SE of their own while users still tried on Area 51 - WRI here is far ahead and should benefit even with a bug report too many here for show?

@gwr Nasser's case is an outlier. He is a long member of the community and this post shouldn't have been removed. Maybe changed to fit the rules but even without it is nice that someone took the time to inspect these integrals.

Usually when bug-tagged questions are closed it's a beginners mistake.

@halirutan I was surprised that WRI is not using the list -- which I believe is coming from Rubi -- as a kind of automatic integration test (in the software development way of usage)?

@gwr Yes, me too. I would be really curious to which extend Wolfram uses serious unit testing at all.

There could have been open communication by marketing then, e.g. we changed this and that for some reason and this may leed to some preliminary regressions but will improve Mathematica in the end... or something similiar.
