The intent is to allow Emacs to compile _any_ Lisp into native code.
The main advantage of that is when the Lisp in question didn't come
with the distribution.  Because otherwise we could just JIT-compile
everything in advance and be done.

IOW, what you mention is a one-time feature, mainly useful to Emacs
developers.  The drawback I mentioned is for the Emacs users, and
AFAIU the JIT feature mainly targets the users.
