I wouldn't go as far as saying it received "a lot" of support, but it did r=
eceive some and i agree it would be nice to have both opcodes being discuss=
ed 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 reques=
t to add CSFS on its own: https://github.com/bitcoin-inquisition/bitcoin/pu=
ll/72.

Looking forward to see some of that.
