There is additionally:
4. load .gdbinit from the inferior's directory

If you are in directory ~ then the .gdbinit file is considered to be
~/.gdbinit (and not inferior .gdbinit).

Does it answer your question?  Do you see any problem with the new behavior.

I have not found a use case where the current behavior is better.

I also agree with "executed before" but in practice it means that if distro
for example (Fedora does not) puts into /etc/gdbinit:
	set auto-load safe-path /opt:/distro-dir:/bin

Then there is no chance to use -iex 'set auto-load safe-path ...' currently.

(One can use add-auto-load-safe-path everywhere which would work, but then
still one cannot remove/reset directories.)
