That's already how I use them.
I've got lists of farmers, musicians, devs, etc... and use these as filters depending on the use case.
No real point in creating a list if it's not to categorize Npubs under an umbrella that useful to you.

So if you have a list called "app developers" and you want to find more developers in your network you'd use a DVM/LLM to find for example my "mobile application devs" which are understood to be roughly the same thing?
I think you might already be able to do this with Unleashed (I'm gonna try):
Start with this list (event id) and find mobile apo developpers in the people they know
Not saying this is going to be as as super accurate, just more accurate than humans trying to stay up to date with everyone occupation and trust level.
How about a list of app developers that is curated by your WoT, so you don’t have to curate it yourself? Bc maybe there are some app devs you’ve never heard of.
