Good morning Jeremy,

>If a sender needs to know the recipient can remove the covenant before spe=
nding, they may request a signature of an challenge string from the recipie=
nts

The recipients can always choose to destroy the privkey after providing the=
 above signature.
Indeed, the recipients can always insist on not cooperating to sign using t=
he taproot branch and thus force spending via the `OP_CHECKOUTPUTSHASHVERIF=
Y`.

Regards,
ZmnSCPxj
