That is already a lot, AFAICT.  use-package's features are generally
present only if they are very useful.

And I don't really understand the urge to have it in the ELisp manual:
a cross-reference to another manual is as easy to follow as a
cross-reference to another node within the same manual.  In many cases
the reader will not even be aware he or she is reading a different
manual.  So what problem do we want to solve by placing the
use-package stuff in the ELisp manual?

If it's just a short mention, probably in The Init File.  But I also
wanted to mention it in the Emacs User manual, where we describe some
simple customizations, and give a couple of examples there.
