In your rush to treat the two as the same, you're neglecting this.

Which distribution would that be?
Although you bring up a nice point.
As long as the distributors handle the details, it doesn't really
matter much what the guts are. The lirc daemon and drivers and
button mappers will be handled transparently.
The problem now isn't so much that lirc is good or bad but that
it isn't integrated with the kernel or most distributions.

It also adds flexibility. Treating the input as more than just
a naeively configured keyboard is rather useful, especially in
a device targeted towards consumer users.

That would be a case of intentionally making things difficult for
yourself when you really don't have to.
