Not actively, but in general it adds more corner cases, which make it 
harder to investigate potential bugs in validation behavior.

Hard to say, but quoting my colleague "about 50%".

Not preventing, but it is something that we need to take into account 
every time we touch the validation code, and so there is a maintenance cost.

Thanks for your input.
