Universal Autofill not honoring "never show in browser"

I'm not seeing value in Collections, but maybe I've not explored it enough. I will revisit the announcement/video about it. At first glance, it seems awkward and inefficient to be continuously flipping between vaults/collections of vaults.

Ironically, not having "All Vaults" selected tripped me up filling forms way more than "never show in browser" did.

Feeling a bit unsupported as a "power user" that read the docs and used the advanced features over the years. Seems several of them have been stripped out and I'm being surprised as I encounter these, but it's too late to voice my dismay really at this stage. While it does happen from time-to-time, I am unaccustomed to features being removed for new software releases typically.

Is there a list of features that were removed so I'm not surprised each time I find one?

How does one participate in whatever surveys there might be for such feature removal in the future?
