I'd guess that makes sense, but I don't entirely understand how the
libalien-wxwidgets-perl <-> libwx-perl connection works, or why we need
a chain of binNMUs after each new upstream wxwidgets3.0 release.

Presumably just copying libwx-perl's dependencies related to this
across would work?

I'd expect so.  There don't seem to be any others - at least I don't see
any other -perl packages in the transition tracker:

https://release.debian.org/transitions/html/wxwidgets3.0-gtk3.html

I added dependencies in my recent libwx-scintilla-perl and
libwx-glcanvas-perl uploads to ensure that a gtk3 version of libwx-perl
was used (and from there down the dependency chain it should be OK).

I didn't try to handle preventing combinations of new libwx-perl with
older libwx-scintilla-perl or libwx-glcanvas-perl though since there was
no evidence that such handling was attempted for previous transitions.

It would certainly be good to address this somehow, but mostly because
it will ease future transitions.  I'm not sure this really deserves to
block this one as the libwx*-perl collection is now back in step across
all release archs:

https://buildd.debian.org/status/package.php?p=libalien-wxwidgets-perl+libwx-perl+libwx-scintilla-perl+libwx-glcanvas-perl

Also blocking the transition really just means that the wx gtk2 packages
can't be removed, yet doing that if anything improves the situation.

But that's mostly a theoretical point right now as the full transition
is going to take months.

Cheers,
