The GNOME project adopted a new versioning scheme last year because with GTK 4 they found it inappropriate to continue having the major number tied to GTK version. The next version following GNOME 3.38 became GNOME 40.0 instead of GNOME 3.40. They released GNOME 41.alpha in July this year.
After this change, the tag gnome3 appears literally applicable only to GNOME 3.x. This year, 46 questions were asked with gnome3 tag. Is having a separate tag for GNOME 3.x still appropriate? Shouldn't the change in versioning be reflected and gnome3 tag dropped altogether by making it a tag synonym of gnome?
There are 41 watchers of gnome3 tag in comparison to 114 watchers of gnome tag. Considering that the tags practically stand for the same for new questions, this unreasonably punishes the poster of the question for choosing a more precise tag.
Assuming that gnome3 stands for "GNOME after GNOME 2", merging gnome3 into gnome allows to prevent confusion under the new versioning scheme. The gnome2 tag still allows to mark questions relevant to GNOME 2, so this should not be an issue. Anyway, there were no questions related to GNOME 2 this year.
Update: I was trying to avoid hoarding multiple questions in one, but the issue of gnome2 tag is related.
The change from GNOME 2 to GNOME 3 was a "rewrite the world event", which GNOME intends to avoid in the future. Tweaking and troubleshooting GNOME 2 and GNOME 3 was different experience. The change caused MATE and Cinnamon into existence. In GNOME 3, there is GNOME Flashback (former GNOME Fallback) session, which is still different as it tries to follow the current GNOME development.
There are many old questions about GNOME 2, starting as early as 2010. However, original authors of questions used the gnome2 tag for the first time in 2014 and for the last time in 2017. It was used by the original authors only 6 times. In the rest 14 cases, the questions were re-tagged by someone else, in most cases long after the question was asked. Should we go on with such re-tagging? The latest question was asked 5 years ago and there are no watchers of the tag.
It would be fair to differentiate between GNOME 2 and GNOME 3, but such differentiation hardly exists in questions by now, other then by
- the version specified in the question and
- by the time of the question.
