What is the proper way to handle the wireguard module now that it's part of the base system?

I just upgraded to FreeBSD 13.2-RELEASE and made sure to deinstall the 
net/wireguard-kmod package before I rebooted. I had to force deinstall it since 
it's still a dependency to net/wireguard. No problems though - VPN-tunnel is up 
with the base kernel module and seems to be working just fine. A few questions 
though:

1) What happens if there are two identically named modules on the system - one 
in /boot/kernel and the other in /boot/modules? Which one gets priority and can 
this be controlled?

2) Depending on the answer to question 1, should I perhaps have left 
net/wireguard-kmod in place? If not, shouldn't there be a check in the Makefile 
for net/wireguard so it doesn't pull in net/wireguard-kmod as a dependency on 
FreeBSD 13.2?
