Tests in core depending on GNU ELPA packages (was: decision on moving core packages to ELPA; also move to obsolete?)

Nice work reorganizing GNU ELPA.

As part of my work on bug#43566, I'd like to add a test to
test/lisp/net/ntlm-tests.el that depends on the GNU ELPA packages
ws-server and url-http-ntlm.  I'd prefer the test to be in core rather
than GNU ELPA, since it's specifically to prevent ntlm.el regressions
introduced by core changes (e.g., url).

Can you suggest a way to accomplish this?

Thanks,
Thomas
