Trying this locally, and it seems like the app always attempts to connect to the cache, even when caching is disabled and no connection string is configured. This presents a problem for retiring the redis cluster previously used for Force's cache.

👋 what's the status of this PR?

[joeyAghion]

Excellent question. There continues to be some requests (1-2k/hr) to the old /api/metaphysics proxying endpoint, but I think it's been long enough that we can comfortably remove it and "break" those clients. @damassi want to rebase and resolve conflicts?

[damassi]

Will do 👍
