Guido is no longer the BDF and spoke fairly positively about this change in the mailing list thread[1].
"To be clear, Sam’s basic approach is a bit slower for single-threaded code,
and he admits that. But to sweeten the pot he has also applied a bunch of
unrelated speedups that make it faster in general, so that overall it’s
always a win. But presumably we could upstream the latter easily,
separately from the GIL-freeing part."
I disagree entirely. The last few releases of Python have made significant changes to the language, coinciding with the project becoming community-led after Guido stepped down.

A lot of that is stuff that is enabled by, or was blocked pending, the new parser; I don't think it was blocked on Guido, and Guido haa hardly stopped being active and influential since stepping down as BDfL
This has been a problem for like 20 years and they have refused fixes before. And there have been fixes. They just don't see this as important
it's practically a religion that its a thing they wont change
