There's no hard and fast rule about what to do with hal components.
I just put the files on github because I don't really expect a lot of
people running Machinekit to need to talk to one of these sensors. If
for some reason it does catch on and become popular, the comp file can
be easily merged into Machinekit.
If anyone does have a HAL component they'd like to share, just add it
to user_comps and send a PR:
