What to check into version control from deno cache?

[andreas-wagner]

Currently I am only checking in the deps folder from the cache, but I noticed there are more folders now.

The folder gen is generated, so no value in checking it in.

The folder registries must be new, most of what I can see are intellisense files (and they change over-and-over polluting my commits).
There is also a new sqlite file named fmt_incremental_cache_v1.

Can somebody please shed some light on what to check-in and what not?
Maybe a general future-proof rule-of-thumb to only exclude the gen folder or something?
