Because they are either require ISA add-on cards and it is quite hard to
find devices that still work, and are supported by the current kernel,
or internal peripherals in devices that are no longer useful. Do you
expect anyone using "Gateway AOL Connected Touchpad" in the year of our
Lord 2024?

I kind of do even if they did not require much involvement.

Let me ask this: why do you want to keep them? Do you know of a large
(or small) userbase of bus mice enthusiasts? Note that it would be very
easy to "git revert" the removal if someone actually needs this.
