Right.

And there's another complication: the release 12 package cannot be 
installed on a 12.1 system. Instead, you must compile that port, and use 
the port mechanism to install the compiled version. This is because some 
internal kernel interface changed between 12.0 and 12.1. I think there's 
a version number, so the 12.1 kernel detects and refuses to load the 
package, which was compiled for 12.0. (Or maybe loads it but refuses to 
run it.) That refusal may be why the obsolete DRM code included in the 
kernel runs, and puts out the "abandonware" message.

This is documented in this DRM bug report:
https://github.com/FreeBSDDesktop/kms-drm/issues/183

If you think this is kind of a mess, then I agree with you. The problem 
is that these kernel modules are distributed as ports/packages, rather 
than with the kernel. That's policy, because the people doing it decided 
that the DRM stuff changes too fast for the kernel release schedule to 
keep up with it. That is not expected to change.
