But ls/stat report information, and find/globs find files.

find -xtype l and *(-@) are common, documented idioms. If only
for that, I don't think the behaviour should be changed.

And it's not clear what the better behaviour would be.

If that broken link should not be matched by *(-W), should it be
matched by *(-^W)? Why? Or should that fail the glob (cause the
shell process to exit)? What about for *(-e:code:)?

Here, you can always work around the problem with *(-W^@).

IMO, the current behaviour, though not ideal is probably the
best you can get (and again, it's consistent with "find"'s).
