To my point of view, if you base your billing from L2 encapsulation you 
gonna bill your customers on local networks problems like, problems on 
L2 frames, padding (as you explain).

These kind of problematic (again to my point of view) is the problem of 
the provider and not of the customer who buy IP traffic and not L2 traffic.
