Read the thread title, but sorry did not spent time to flip through all these long conversations.
I’m not doing monster size game designs, only your average TV stuff.
So I don’t complicate my life …I’m an old grumpy fellow coming from pro analog and tape… 
You brought up " clip packages " and that is the only way I work if repeatable, easily searchable files are in need.
Have a template with bunch of tracks, groups, fxs sends etc…
I work from there to build my effects, export clip groups appropriately named and store them in a “custom fxs” folder.
Also, as I need to do quite a few foreign versioning all my announcement, contacts and similar VO’s get the same clip structure and can easily called back in a session…
just saying…
