comment Why use variable p, q, g for Diffie-Hellman?
Isn't that an advantage of standard groups? Since for those you can easily check if they were generated properly e.g. checking that the $p$ is a safe prime, or that the groups is a schnorr group with properly sized factors.

comment Why use variable p, q, g for Diffie-Hellman?
What's the problem of the knowing factorization of the order? AFAIK it is usually known. Finite fields used with DH are usually based on a safe prime or are schnorr-groups. In both cases the prime factors of the order are known.
