I've proposed five patches to the jpms-spec-experts list [1..5] for
discussion. The patches are as follows:

3. Layer primitive: addPackage() - allows ModuleLayer.Controllers to
add packages to a module after it has been defined
[...]
However for #3 then you've missed several important error cases, e.g.
illegal package names, or the package is already in another module
defined to the class loader. There is impact in other areas too.
I wasn't worried about validating package names at first, because I
figured that you could never define a class to the package anyway, but
nevertheless I see the value in error detection (and avoiding piles of
cruft inside the JVM regardless of whether it might trip any kind of
internal assertion, which I acknowledge as a possibility as well), so
I've pushed up a patch [1] to add package name validation. This also
detects the empty package name situation.
Detecting package conflict is somewhat more subtle; that's coming up next.
