The documentation says that only the CPU and DDR PLLs can be dynamically
changed after boot.

The question is what exactly is meant by after boot. :) Anyway, if the
kernel has no business changing some other PLLs, if there's code for
changing them, should it be dropped?

No, because all the other PLLs may not be initialized by the U-boot
(audio, video, gpu...), and also, their rate may be changed safely by
stopping them (gate).
