connected-sets and connectedness?

Tag connected-sets was created here a few days ago, and it was later removed.

I thought that, in order to be consistent, if we have tag for compactness then connectedness could be equally important. (And connectedness seemed to me better name than connected-sets.)

I even prepared some rough draft of tag-excerpt: Use this tag for question on connected spaces and various related notions (connected components, locally connected spaces, path-connected spaces, arcwise connected spaces,totally disconnected spaces,...)

Several related properties are studied in topology:

After the tag was removed, I did nothing.

Today connectedness appeared among new tags; it was created in this question, which is about connectedness in graph theory.

So the question is: Do we want connectedness? Should it be only for the meaning of this word in general topology, of for other meanings too? (Apart from topology and graph theory, Wikipedia mentions connected categories. Although I don't think there will be many questions about them.)

BTW some of the tags from new tags tab are already discussed at meta.

pronunciation has 6 questions, it was discussed here.

geometric-algebra as 6 questions, it was discussed here.
