Weren't some of these widespread conventions in some sense strategically designed or implemented in such a way as to ensure backdoors and/or contrived vulnerabillities? Something, something purposefully smaller key sizes or special "weaker" variables than was practicable or other trickery that always ostensibly has an economic or other seemingly justifiable underpinning but introduces unacceptable security compromises that arise later and predictably.

Historically there have been restrictions on key size (and bad algorithms) - to my knowledge, neither is currently the case: there is no known way to break a 2048-bit RSA key (although if there was, we probably wouldn't know about it)
