Personally, I don't think that it's even a right format for questions which are not part of a larger discussion (e.g. deciding on details of some issue or PR).
I have never seen link to gitter in google search results, and answers vanishing forever (not sure how good gitter search is though) does not sound good. Once I joined a few channels because I wanted to ask maintainers a quick question if $xyz sounds feasible or am I strongly misunderstanding things, because had some ideas how I could contribute. These were rather popular repos and all channels were full of low effort questions that could be either google-able or answered by spending a few minutes playing around.
