The current state of “seed” investing

What I've thought for a while is: maybe we need to just deprecate what might be a bunch of arcane and no longer meaningful terminology.

It's a "round." Your company's metrics are X and you are seeking $N at pre-money $M. Maybe just number them: R1, R2, etc.

Or even better drop the whole concept of a 'round' in favor of something more high-resolution. But that would require a lot of re-engineering of legal frameworks, which is hard.
