I was hoping for more of a technical explanation, but I think I understand
after re-reading the earlier comments. The plugin developer would provide DBIC
schema files with the plugin in the lib directory, and if the plugin is loaded
early enough, then Koha::Database will detect them?

I am all for using DBIC schema files. It would make plugins a lot easier to
write.

However, wouldn't that mean that you'd have to restart Starman before being
able to use the plugin? Shouldn't that requirement should be surfaced to users
(even if only as a warning)?

Since koha-plack uses bash, we could try something like the following (although
I admit it uses bash magic I haven't fully understood yet):

[[ ":$PATH:" != *":/path/to/add:"* ]] && PATH="${PATH}:/path/to/add"
