The code from #32744 was released with Sage 9.5 and has since been real-world tested by numerous people. It is exceedingly unlikely that we'll want to remove it, and I'm reasonably convinced that there are no disastrous bugs.

Therefore I propose to remove the experimental warning in the next release. See also #34303 comment:18.

In the future, we should also change the default composition method to EllipticCurveHom_composite: See #34410.
