Yes, supported: Having #p"foo.asd" define systems "foo/test",
"foo/bar", "foo/baz" in addition to "foo". ASDF can even find them if
you (asdf:make :foo/test) without having loaded foo first.

Unsupported: Having #p"foo.asd" define "foo-test", "bar",
"foo-unparsable-mess_with.angry^#$*characters", etc.

Please use secondary systems that are properly named. I <3
secondary/systems. The slash ensures ASDF can find your secondary

See https://gitlab.common-lisp.net/asdf/asdf/merge_requests/51 for the
proposed change: issuing a WARNING (not an ERROR, so your builds won't
break, and the warning does not happen within a COMPILE-FILE either).
