RFC7626 was IMO quite important in enabling those later
protocols, so that age and sequence are signs of success.

I'm not sure what point you're making there tbh, but I
don't believe 7626 is OBE when it comes to considering
privacy issues arising from interactions between recursives
and TLDs, which is a big part of what we're discussing
here I hope.
