Looks good to me. It will get in the queue of reverse depends runs to do.

Just for kicks: when/why did we need this? When could that have been true?

git-blame says that this is from 20 years ago, and Rcpp is 18 years old, so... never.

No, it says @kevinushey did this in 2015:
454de74f5 (Kevin Ushey 2015-07-13 17:45:01 -0700 59) if (identity == R_UnboundValue) {
454de74f5 (Kevin Ushey 2015-07-13 17:45:01 -0700 60) stop("Failed to find 'base::identity()'");
1c90562c8 (Kevin Ushey 2015-07-13 15:43:09 -0700 61) }
(i.e. I was asking why we added this / why we can now simply remove it).

That simplification seems almost too good to be true. Why did we not do that earlier? 😆

Closes #1465.
For promises, we have here a temporary workaround, but this is going to come back at us, because we are using a bunch of functions (
PRVALUE,PRENV...) that are not part of the API, even if we don't see a NOTE yet. The problem is that I don't see alternatives yet.Checklist
