Yes, this seems to break the situation where a wallet wants to use NOINPUT for 
everything, including normal L1 payments. For example, in the scenario where 
address reuse will be rejected/ignored by the recipient unconditionally, and 
the payee is considered to have burned their bitcoins by attempting it.
