I've flagged this as a consensus breaking change as it adds an intrinsic to the web-assembly interface. Even though this is intended to be a privileged intrinsic we cannot guarantee backwards compatibility to any EOSIO-based blockchain with this PR as spec'd.

We do have features, on schedule for the next release, which address this in a way that affords EOSIO-based chains a definable path for maintaining original functions and adding/modifying consensus rules in the same code base.

You can read more here #6429

A compliant version of this change will also depend on #6437
