One way to do a URSF is to reject the block *after* BIP110's activation block unless it contains a tx that violates one of BIP110's restrictions. If enough people run it, miners have to choose: make t...
No miners are currently signaling support for BIP110, so investing time and effort in developing a URSF client seems like a waste of time and effort at this time (to me, anyways).
Much easier to just use the rejectblock command post-fork if a BIP110 block that forks the chain is ever mined.
