I thought Roger made all of them decisions ;)

I think this is a fine plan for now, at least for the next n tags. We
know it's only a matter of time before it will be deprecated, but I
think it's worth squeezing as much out of them as possible.

at a future time when the arms race nears equilibrium (as far as we
can tell).
