Currently, we have Christoph Berg writing "I'd say the ship has sailed, a new
release would now break things the other way round." and you writing in favor
of undoing. It think it boils down to whether you want N people to recompile
twice or M>N people to recompile once, where we don't know N or M except that
M > N. Fortunately, the N are probably fairly well represented in this
thread. So to all: please speak up by 2024-11-16T17:00+0000 if you think it's
the wrong choice to bring back the v16.4 ABI and tell people to rebuild
extensions built against v16.5 (likewise for corresponding versions of
v14-v17). Currently, the plan of record is to do that.
