Just a question/suggestion for an item. I had started a patch that converted all node UI and python references from "fac" to "factor" to be much more user-friendly. I was directed to shelve that patch until 4.0, and am certainly keen to make those changes at that time. Is it possible to reference archived patches or would a new issue/milestone need to be opened? Or would this get added to item #102607?

The "fac" rename is part of the already listed #96219.

There's almost 200 instances of DNA_DEPRECATED across many DNA types. Removing those deprecated fields would be really nice to do for 4.0. Will there be a task to detail what's required to safely do so wrt back-compat etc?
