Do we *really* need to be tagging national speed limits on individual

E.g. the vast majority of roads ought to be one of;

Perhaps we could tag the ones that differ from the above - and let
post-processors add national defaults as necessary?
Spot on.

I use to think this but here in North Hampshire they've been scattering
speed limits all over the place and to settle on a default would be
quite hard. For example none of the single carriage way A-roads near me
have the national speed limit on them (rural or not).
The advantage of a tag on each way (whatever it might be) is that I know
what the speed limit on that road is; no tag could easily mean it just
hasn't been surveyed.
