Per offline confusion/discussion: I plan to work on a grease feature
for beta _regardless_ of whether a "production-grade"
max_protocol_version=grease option turns out to be viable before
feature freeze; do not feel like you "have" to put work into the
latter just to get the former. Sorry about that.
