Paul you should refine your grep. Lastly there were some libraries that 
changed already from math:: to integer.

IMO, the single library I see is using math::gcd/lcm is multiprecision, 
and I'm not sure removing this dependency is really needed.
Please provide the result of your grep.

I don't think we should remove math::gcd/lcm, just forward to the 
interger::gcd/lcm.

Best,
