OP_Return outputs

Sjors Provoost suggested that I email this mailing list as notice of my intent
to get a pull-req merged that would remove the arbitrary 80-byte, 1 output /
tx, standardness restrictions on OP_Return outputs. His rationale was that
removing these standardness restrictions could potentially open up additional
transaction pinning(1) vectors. Since this is a potential problem with any
relaxation of standardness rules, I don't consider this to be an important
concern. But consider this email your notice.

At least some miners appear to be mining non-bitcoin-core-standard
transactions. So with respect to the hash power of those miners these pinning
vectors may in fact exist already.
