This does NOT mean Python will get Tail Call Optimization, as Guido cannot be shown The Light, and has decided.

Guido is no longer BDFL though, it's the steering committee that decides.

the steering committee seems way less conservative than Guido, right?

Looking at python from the outside a lot of changes since GvR stepped down seem like stuff he'd not have been fond of.

Any examples? The biggest change since Guido stepped down has been the addition of pattern matching, which he was strongly in favour of.

Moreover, Guido is in favour of ongoing addition of major new features (like pattern matching), worrying that without them Python would become a “legacy language”:

I was thinking of the walrus operator, various f-string changes, relenting on the "GIL removal must not cost performance" stance (although"covered" by other improvements), things like that.

I don't follow python closely so it may 100% be stuff that GvR endorsed too, or I'm mixing up the timelines. It just feels to me that python is changing much faster than it did in the 2.x days.

This may just be time passing faster now that you're older.

I think part of the reason Guido stepped down was that the BDFL structure created too much load on him dealing with actual and potential change, so its unsurprising that the rate of change increased when the governance structure changed to one that managed change without imposing the same load on a particular individual.
