That's a choice, obviously, you can configure the resolution with either, both, and in whatever order you want. The warnings are a consequence of those choices (and they really shouldn't be warnings, the logging is too high).

That will be a hassle to maintain, it's very brittle. LocalDynamic is a better way to handle piles of metadata if you even need or want to use it at all.

If you don't use the metadata to do anything, there's little point in moving to it. For those of us that use metadata for everything (not that I use CAS, but the same principle will apply to OIDC), being able to is very valuable.
