I used to hot-plug AT keyboards all the time. Then one time at work,
the system died as soon as I unplugged the keyboard, and wouldn't
even power up after that. When I called the repair crew they said,
"You can't do that!" and sent someone out to replace the mobo. I
figured it was just poor design on Compaq's part, so I just stopped
hot-plugging Compaqs after that. Then a few years later I killed
one of my own systems (generic Taiwanese 486/VLB mobo) the same way,
and decided that hot-plugging PC keyboards really is a bad idea.
(I managed to resurrect this mobo by finding and removing the
burned-out component, and soldering on a new one.)
I still use keyboard switchboxes, and have never had a problem with
them.
As far as I know, AT-style and PS/2-style keyboards are electrically
identical -- the only difference is the size of the connector.
