Sounds good to me, thanks.  We'll take patches implementing this.

Currently, setting package-native-compile to t will make package-install
asynchronously native-compile the package.  This works great for
interactive usage.

However, this is unsuitable for a batch Emacs running package-install.
"emacs -batch --eval (package-install something)" will exit once the
package is installed, but before the asynchronous native compilation
completes; the native compilation will just be abandoned.  So,
currently, there's no straightforward way to native compile a package
from a batch Emacs.

Running package-install from a batch Emacs is useful as a way to update
or pre-install packages in scripts, without requiring user interaction.
This is widely used by package managers like Nix or dpkg to install
Emacs packages as OS packages.  In my specific case, it's used to
install and byte-compile common packages into site-lisp.  In all these
cases, it would be nice to be able to native-compile the package at
installation time and include the .eln files in the package directory.

A straightforward solution would be for package-install-file to support
synchronously native-compiling the installed package, such that after
package-install finishes running, the native compilation is complete.
Perhaps with a new value of package-native-compile?
