Ayep. You'll notice it has a single ps/2 port available. For mouse or
keyboard, not both.

Don't quote me, but I think those PS/2 ports that are half green/half
purple can cope with a 'Y' splitter

There are sufficient pins on the miniDIN to host two
PS/2 electrical interfaces. Clock,Data for one, plus
Clock,Data for a second interface. The remaining pins
are power,ground.

Once a PS/2 is spotted on the motherboard, it means
there is a SuperI/O chip on the motherboard, and it's
just as easy to support one PS/2 as two PS/2. SuperI/O
exist in various stripped-down forms, but I don't think
there's much incentive to strip off the second clock,data
pair. The chip might typically be present so there
can be a working Hardware Monitor interface.

And to me, PS/2 is one of the most trouble-free interfaces
in terms of drivers. Never seems to be a problem.
