I'm not convinced that's true. Already in this thread someone is blaming 
large changesets purely because the verifying software they're using 
isn't capable of dealing with them. Judge on quality not quantity.

Tenuous & assumptive.
It was just one "example".

Just because you believe that, it doesn't make it so.
Knowledge which effects OSM comes from many sources:
A walk though town where a new shop has opened, or BBC world news which 
reports how a Far Eastern bridge building project has been cancelled & 
the proposed data requires removing.

These rules require amending as they're based purely on size & the 
criticism is usually in the form of " "You dumbass, why did you create a 
world-spanning changeset?". Judge on quality not quantity.

I'm not convinced. This perception only occurs because changesets over 
large areas stand out.
