How is that weird? `plist-get' might, once in a while, be useful to
call on potentially malicious data. Fequal isn't, so `lax-plist-get'
cannot be, either.

(Fequal can signal, and it's easy to construct objects which will lock
up Emacs for many minutes when compared with Fequal. I think the
latter issue should be fixed, FWIW).
