By "it" you mean both features?

I've seen some reference to the pgtk branch in another message but that
seemed to be a minor issue when using pgtk.

So now I'm wondering: what do you think should be the criteria for
inclusion into `master`?

As written above, I thought the plan was to include those as
experimental features for Emacs-28.1, so I thought the criteria were
going to be something like:
- Code is clean enough: doesn't risk introducing regressions into the rest
  of the code.
- It's very likely that the feature will reach maturity (i.e. lose
  the "experimental" label) in some not too distant future.
- It's already usable enough that most people who're looking forward to
  this feature will be fairly satisfied if they try it (it might still
  have some rough edges, but by and large it works).

Leaving a feature waiting on a branch for extended period of time
imposes a lot of extra work to keep it up to date (and it can very
discouraging to have to do that if there's no clear set of "things
missing").
