Why disable something that will never happen?

I think the Debian case is not relevant, because they provide all the
*.eln files with the package you install (or so I understand).  So
either the user will only use those packages where *.eln are already
provided (in which case there's no reason to disable anything), or
they will want to use packages outside of the Debian distribution, in
which case I'm asking why they would like to give up on compiling
those additional ones.

What is "it" in "do it" above?  And what does the 2000 number counts
here? are you talking about 2000 Emacs Lisp packages that are not
bundled with the Emacs distribution and need to be installed
separately?  Or are you counting some other kind of "packages"?

I don't see how disabling JIT compilation is needed for these 3
purposes.  In particular, if all the *.eln files are already present,
there will be no need to recompile them.
