It natural place in the emacs source tree should be the exact layout used
for ELPA, without any rearrangement. You proposal requires rearranging
the sources for the convenience of the few emacs develoeprs rather than
the manu emacs users. I do not think that is the right approach.

It is a pointless rearrangement from the package format, and makes emacs
core needlessly different from the package distribution. Bundling with
emacs core or distributing separately via ELPA should only concern how a
package is delivered, but should not change its content or layout.

Then you have lost me, as your proposal in this thread seems to be to
keeo the existing emacs directory structure, and make the layout of
packages bundled with emacs be different from the layout of the same
packages in ELPA.

The existing emacs source tree directory structure is sensible for a
monolithic project. However the whole idea here is to move away from a
monolithic structure, so the source tree contains only the emacs
core. Unmodified ELPA packages are imported into a packages directory
to be bundled for distribution.
