Hi Jakub & Gerald,
first, thanks for all the suggestions!
I have now followed Gerald's suggestion to place the table into the main
GOMP page.
I then also decided to make it more GCC-user orientated than
GCC-developer orientated by re-writing the intro (but keeping the old
one as background), also referencing OpenACC, mentioning the
command-line arguments to use + adding a bunch of GCC links to have
everything together.
Thoughts on this part?
I also added the first OpenMP entry to gcc-13/changes.html, which also
links to the GOMP page. (I expect more mainline commits in the near
feature, but I want to have a stub there. I think the next update could
be done in a month or two – once more items have accumulated.)
And I tried to incorporate all suggested changes. Regarding:

I think we should have also 2.5, 3.0, 3.1 and 4.0 entries in the above list,
with similar style as the OpenMP 4.5 entry.
...
Though, maybe a table form for the 2.5-4.5 versions would be more consistent
with the rest,
Partially because I am lazy and partially because I think a table with
those entries looks odd, I went for the bullet style.
+<tr><td>Map-order clarifications</td><td>GCC?</td><td></td></tr>
This entry I gave up on, it isn't exactly clear to me what that
bullet is about and once we figure that out, we need to do some archeology
on whether we support it at all and if yes, since which commit and thus
since which GCC version.
I concur – but the question is how to handle it now? Leave it and
correct it later? Comment/remove it?
Can you check whether you now like the bullet points? If so, I will
update the .texi to match.
