I wouldn't go as far as saying it received "a lot" of support, but it did receive some and i agree it would be nice to have both opcodes being discussed on Signet.

The PR adding it to inquisition last year as part of LNHANCE was abandoned and closed a few months ago. Greg Sanders recently opened a WIP pull request to add CSFS on its own: https://github.com/bitcoin-inquisition/bitcoin/pull/72.

Looking forward to see some of that.

This also allows applications relying on CTV + CSFS to develop further.
