Thanks Jakob for the quick follow-up. 
Would that be a potential enhancement?
Similar to geometry.remove.width-tolerance, you could set a threshold? 
I am asking because I am using meso, and as discussed previously, short edges 
have adverse effects  (and this seems to propagate onto other edges as well).
