It's best to keep changes self-contained *per package*, i.e. one commit
per package changed.

I think since these search paths appear to be reused often, they should
be defined in the (guix search-paths) modules for easy reuse.

You seem to be adding these search paths to *plugins*, which is
unexpected from my understanding: a plugins by itself does nothing; the
search paths should rather be defined on the consumer of the plugins
(e.g. Ardour), no?
