Because no one would consider it, or because careful expert analysis isn't enough and no one would trust it? In the latter case, how does one get on the trusted list, and if NSA is on it how on earth does one get off?
I think you're seriously underestimating how insular this community is. The phenomenon you're describing really just doesn't happen. You build a reputation among cryptographers and build to the point where your designs are seriously considered as standards.
Yes I probably am. The reputation shortcut seems to have worked for the community so far, so anonymous crypto designers don't really have anything to complain about.
