Great, thanks for confirming.

+1. I used to edit the subject like to say "Intent to Deprecate" (i.e.
remove the "and Remove") but that broke some of the tooling, so now I don't
touch it. But I do wish the descriptions changed to say "deprecation"
instead of "dev trial" and "remove" instead of "ship".

Sure, that makes sense. I think at that point there might be more data to
pull into the explainer also.

I agree, it'd be nice to see the use counters go down before that, but I
always notice that deprecating things seems to make usage go up. I don't
have a great estimate for the removal timeline - I'm following Mozilla's
lead on this, and ideally they turn it off by default first for a while,
before Blink does. Sorry I don't have a more definite schedule!

Yep, thanks.

Unclear to me also, but I'm hopeful.

Thanks, everyone!
