Just pointing at the message where this has been discussed previously,
for reference:

Leaving Solaris aside because there is nothing older than 11 in the
buildfarm currently, I am dubious that it is a good idea to remove
this code knowing that we have a thread from a few months ago about
the fact that we have folks complaining about AIX support and that we
should bring it back:
