Yes, it means the docstring are fetched from the likes of
`lisp/files.elc` (as is already the case for the non-preloaded files)
instead of from `etc/DOC`.

No, the `.el` files are not used any more than before.

I don't think this has any impact.

The only non-trivial consequence I can think of is when the compiled
preloaded files are missing.  E.g. if the distros remove
`lisp/files.elc`.  I don't aware of any distro/packaging doing it (even
tho it did make sense doing so to save a few bytes).
