Yeah, thinking about it a bit more, the new code makes it much easier to
change the default value if that's something we want, so for now I'll
move these at the end (ie. make them turn `true` into `false` in the
last column of their respective line), and send this as a v2 tomorrow,
with any other comment I would've received in the mean time addressed,
that way they'll be trivial to drop without affecting the code.
