Can you give a concrete example where it is actually more powerful?
Something that can be expressed with "restrictions 1.5", but not with
the "extended conditions" syntax?

(Yes, it lists "more of the same" - more vehicle types, more groups of
users, more weather conditions and so on. But that's not what I mean.
These things don't have anything to do with the syntax.)

More reasonable than "access:lgv?wet.speed", yes. But how is it easier
than "maxspeed:hgv:wet"?
