When a relayer that does not also serve (i.e. it keeps no history file)
checks a Date for staleness, what cut-off does it use? Presumably an
arbitrary number such as 14 days. Yes, that could be written in, but we
would need to agree a number.
In the case of a server, there is no arbitrariness, because the cut-off is
determined solely by the length of time it keeps history around (which is
what my text currently says).
So what would you like me to say in the case of pure relayers?
