We can set optimization level in init file, or early init, and that will
affect how lisp files are compiled, so for some advanced users
precompiled binaries are of not so much use.

For some less advanced users, maybe with slower computers, precompiled
binaries could save some time and computer resource.

I have personally no inclination for either yes or no, just wanted to
add some arguments to the discussion.
