yes, everything has USB ports, so they could use USB keyboards, but it's
actually pretty common to still use PS/2 keyboards (and while the systems
all support USB, it's not uncommon to have KVM systems, including pretty
expensive 'enterprise' KVM systems that still require PS/2 keyboards be
used to plug into the KVM, so those are the keyboards that are in the
datacenter that someone will grab to plug into a problem machine)

The server hardware I've looked at will all declare the ports regardless
of whether or not there's something plugged in.

remember that many people use systems in datacenters that are not 'server 
hardware'.

when a desktop PC can have 4-6 cores with 8G+ of ram and a couple TB of 
storage, a lot of people will end up using those systems for production.

As they grow into bigger companies they will shift to 'server class' 
hardware, but startups tend to use whatever they can scrounge (or buy 
_really_ cheap)

By the way, for what it's worth I think it's a very bad idea to hot-plug 
PS/2 keyboards. The hardware may be better nowadays, but back when I was a 
PC repair tech I made very good money replacing the fuses on motherboards 
that would blow because someone hot-plugged the keyboard.

That said, there are times when it happens, and many people don't see any 
problem with it.
