couldpresent itself since, just like extension creation, all the flag does is allow the user to become a superuser for
purposesof installing (or removing) the extension objects. Per Tom, the pre-v14 drop behavior is indeed a bug. It is
notgoing to be back-patched, nor has the documentation been updated to say that DROP EXTENSION is effectively prevented
dueto the existence of this bug (if you really need superuser to install the extension it seems reasonable it requires
thesame to drop it).

I have the same opinion on this. In v14 it seems to me that this has
been fixed by a side-effect of the commit b1d32d3. Looking at the
discussion of the commit, there is no discussion on this behavior
change.
While this behavior contradicts what the doc says ("This configuration
gives the calling user the right to drop the extension, but not to
modify individual objects within it) I also understand that it would
be better to avoid the risk of moving/removing superuser checks in
v13. So far the reported issues are only about making bloom trusted,
which seems not a common use case (right?). So probably we can come
back to this issue and discuss how to fix this issue in v13 when more
issues related to this bug are reported.
