Have you considered Conditional restrictions[1]? You mentioned them as
one of the existing tagging solutions (you had "80 @ winter" as the
example), and to me, they seem like a good fit. It makes a certain
intuitive sense to treat seasons similarly to how we already treat dates
and weather.

If I understand the approved "Dynamic maxspeed" proposal[2] correctly,
it suggests tagging the maximum maxspeed using the regular maxspeed tag,
and adding maxspeed:variable=yes to indicate that the maxspeed is variable.
