How did the Koblitz/Menezes papers affect the cryptography community?
My impression (which is limited) is that the most researchers are pretty content with the state of security proofs, and it did not have much impact on changing the research agenda of the community. In fact, a related paper was strongly opposed by leading cryptographers. That is not to say the papers were ignored. They generated lots of discussion and maybe some self-reflection. 

They are also, unfortunately, sometimes cited by people who do not really understand the issues and just have an axe to grind against papers being too technical.
