The "No Taproot" section of the Sapio docs need updating :) What are
your plans to take advantage of Taproot with Sapio? It would have been
interesting to see what a Taproot emulator would have looked like,
although no need for it now. It seems to me Taproot would have been
harder to emulate than CTV though I could be wrong.
https://learn.sapio-lang.org/ch05-02-taproot.html
Also there have been a number of people asking questions about Sapio
and CTV on the Libera equivalents of Freenode channels #sapio and
##ctv-bip-review over the past months. Do you plan to join and claim
those channels?

This has actually never been true (Sapio assumes extensions).
If the extensions are not present, you can stub them out with a signing
federation instead, configurable as flags, and you can also write many
contracts that do not use the ctv based components at all.
The protocol for emulation is a bit clever (if I do say so myself) since it
ensures that contract compilation is completely offline and the oracles are
completely stateless.
