OK. It's in a polygon so the implications aren't so important, but 
surely this is a good thing. Don't you want a vendor that comes 
back to you on out-of-spec issues ? 

Do you want a bucket chemist to second guess your design ?
If you don't mind them shorted, why didn't you make it solid ?
Should you specify which rules to ignore ?
Does the DRC only apply to the tracks that pass ?

> I have never heard of this before. (30 years experience)

Doesn't that concern you ? For 30 years your vendors have 
accepted board designs that they know are outside of their 
manufacturing capabilities ?
They probably all have ISO9000 too.

> Anyone else in the group heard of this?

Functional Quality Control ? It's a marketing term isn't it ?
