Why is a +weight malus *very* hardforky?
Suppose a new version of a node adds, say, +20 sipa per output of a transaction (in order to economically discourage the creation of additional outputs in the UTXO set).
Older versions would see the block as being lower weight than usual, but as the consensus rule is "smaller than 4Msipa" they should still accept any block acceptable to newer versions.
It seems to me that only a -weight bonus is hardforky (but then xref SegWit and its -weight bonus on inputs).
I suppose the effect is primarily felt on mining nodes?
Miners might refuse to activate such a fork, as they would see fewer transactions per block on average?
Regards,
