Non-blocking, just noting something here: we ought to come up with guidelines for whether to summarize the alternatives in the description or not.

Instead of junk-drawer-ing these (and having to do exceptional things with the name and identifier) maybe we can give them a real name?

Yikes, this one is messy. According to https://caniuse.com/css-overflow-overlay, this has a rather different between versions that BCD doesn't capture at all. I suspect what this needs is new support statements in BCD, showing partial_implementation when browsers had the non-standard behavior (i.e., before they aliased to auto).
Maybe we thread this needle like this:
| description: "The `overflow: overlay` CSS declaration sets the behavior for when content doesn't fit in an element. It is superceded by `overflow: auto`." | |
| description: "The `overflow: overlay` CSS declaration is an alias to `overflow: auto`. However, non-standard historic implementations change the appearance of scrollbars when content doesn't fit in an element." |
And then keep this whole file in drafts until we (I?) can do the work upstream.
(cc: @atopal this is another good example of a "feature" that is interoperable—overflow: overlay aliasing to overflow: auto—but a bad thing to describe as Baseline)

Let's write these in the usual way (present-tense, not incorporating the "deprecation"):

I think this is more inline with our "not to be confused with" and "also known as". I suspect we'll soon need a style guide entry for these.

Let's line this up closer to the other writing-mode features
