The minor updates may be worth having but all too often I find that they
are not that useful. For example, long stretch of motorway with very
long-term roadworks, eventually gets updated to set speed limit of 50
there, and it is still 50 though the works finished many months ago.

Well change it yourself.
Tomtoms that use map share updates have the ability for the user to change
stuff like speed limits.
