Yes, almost all of Savar's updates go beyond simple fixes and they were in some cases published years apart. In my private worksheet, I usually give different scores to each version of a mission, due to map or gameplay differences. All arguments for separate entries on Thief Guild.
The main point, therefore, is consistency: There should be either at least two entries for each mission, one for each version, or each mission should have only one entry, regardless of version differences.
I'm kind of not following the main point.
@Username you suggest to merge v2.0 and v3.0 pages into one, and list the changes in the notes section.
But the changes between v2.0 and v3.0 (as you write it) "went beyond simple fixes". The same is v1.3 vs v2.0.
I think Morente is giving a good example with Scarlet Cascabel. The changes are beyond fixes and have time distance. Both those aspects are present in The Hotel versions. Why shouldn't they have separate pages?
Here are my TTLG posts on changes I noticed in different versions of The Hotel.

@Username what are the changelogs of
The Hotel
v1.6 2009
v2.0 2010
v3.0 2015
I prepared notes while I played through all the different versions of Savar's T3 missions that were still available. I can upload version changelogs if that approach is what we decide on.
The only thing that would have to be done first is to merge the two entries of Savar's T3 mission The Hotel into one.
I'd pursue your idea with the changes appearing in the notes. There are sometimes multiple entries for T1 or T2 FMs as well but these are often different releases and not updates (e.g. the Scarlet Cascabel).
Having a kind of changelog in the notes sounds perfect to me and circumvents any confusion
