Unless you mean "hosts that disabled PDO"… I think they can safely be ignored.
Most Linux/BSD distributions seem to separate out "core" PHP extensions (those that are distributed with php source, not via peel) into individual packages.
So while PDO may not be installed by a plain `apt-get install php5` or similar, I doubt the now deprecated `mysql` extension is installed by "default" in those scenarios either.
Edit: this approach also means that the PDO extension in php.ini will be commented, because its loaded by a package specific ini file e.g. /etc/php/7.0/fpm/conf.d/* which are generally symlinks to /etc/php/7.0/mods-available/
I don't really understand your point. WordPress is ubiquitous. Until today I've never heard of MODX Revolution.
Commented out in php.ini does mean disabled - as in not enabled. PDO isn't enabled by default in FreeBSD you still need to install a separate package for PDO.
His/Her point was that if someone is still using shared hosting (where they can't change the extensions available) it would be very rare to find one that doesn't have PDO enabled.
