No dance required, as the default has been so that it just works for
a while now (so you install FreeBSD 13 and do "pkg install xorg",
everything just works out of the box). It's the opposite now, you need
to tweak kern.evdev.rcpt_mask now to get old input methods working
(e.g., when using ancient serial mice, you need to set it to 3).

With kern.evdev.rcpt_mask=12 (the default setting), only mouse hardware
and keyboard hardware are receiving events. It might have worked
if you changed it to 6 (to get keyboard) or 3 (to get keyboard and
mouse). But not really relevant for you anymore, as you have a working
setup now.

For better or worse, upstream development is focused on libinput and
many modern devices only work with it to their full potential. So,
unless you have some old beloved piece of hardware that isn't supported
and absolutely requires the classic way of doing things, there is no
point in making your life harder by not using it.
