I agree with your main points.
One small thing. You can report bugs for Trisquel 6.0 mini.
[https://trisquel.info/en/issues/7110 This bug is one such example]. That is
possible.
I also work on the bug tracker as a volunteer. There are multiple problems.
Part of the problem is we have a too many bugs and not enough help. Some
bugs are in other languages. Some bugs are not described very well. Many
bugs could be reported upstream because they impact Ubuntu/Debian as well.
If they were to fix it we would benefit as well. Another issue is we do have
some [https://trisquel.info/en/issues/5311 critical freedom related bugs].
These take priority in terms of trying to get them fixed.
Again I am just a volunteer but these are some of my perceived problems. If
you are interested in working on this issue please check out

page about trying to get these issues fixed.]
