As long as an unspendable outputs (OP_RETURN outputs for example) with
amount=3D0 are still allowed I don't see it being an issue for anything.

Right now it is possible to create 0-value outputs that are spendable<br>
and thus stay in the utxo (potentially forever). Requiring at least 1<br>
satoshi per output doesn&#39;t really do much against a spam attack to the<=
br>
utxo, but I think it would be slightly better than the current<br>
situation.<br>
<br>
Is there any reason or use case to keep allowing spendable outputs<br>
with null amounts in them?<br>
<br>
If not, I&#39;m happy to create a BIP with its code, this should be simple.=
