Just to be clear, it's not bower itself (the command-line tool) that needs
packaging, just the components that bower itself packages.

Well, no, but at least it exists ;)

I'm not sure what the difference is (unless it's just related to the
Debian-specific historical issue you raise below). xstatic and bower are
remarkably similar a directory to be packaged and some meta-data describing

The dependencies won't be bumped any faster than reviewers allow, though I
realise that's not necessarily going to make you sleep any easier. Hmm.

Again; bower is not npm! Jasmine is a command-line program which is
packaged by npm. Bower packages bundles of stuff that are included in web
applications. bower itself, a command-line tool, is packaged by npm, but
itself manages other packages which are not command-line things, but just
applications to use.

That is unfortunate. It may be that Debian therefore has to special-case
angular to handle that case.
I think the general idea of following the component pattern set by bower
(separate directories with no risk of conflicts, and using the bower.json
meta-data to allow automatic configuration of the component) is too good to
dismiss though. Far less work for everyone, including packagers.
Perhaps the new packages should have "bower" in their name?

Yep. There is the bower.json file which we'll have in Horizon
