Sergio there is no "abuse" there,  OP_NOP3 in that case would be
redefined to OP_COINBASE_FOO_CONSISTENCY.

(I say FOO because it's not clear what rule you actually hope to apply there.)

What you suggested has no purpose by itself: it would need an
additional change which overlays functionality in order to actually do
something. Such a change would likely be "ugly"-- it's easy to be
elegant when you do nothing.
