I spent time talking to Dan and Tanja this weekend at ShmooCon about this

Yes, it does. This would fix the single major flaw of Curve25519 --
concatenating base-10 numbers to spell out a tuple just doesn't make sense
(except as a trap, so that if anyone reads it out as "twenty-five thousand
..." you'll know they don't know what they're saying).  I also don't really
like having whitespace in those names, so I'd prefer "Curve-255-19" over
"Curve 255-19".

("Curve" isn't very descriptive, but I've yet to see a more descriptive
name for this curve that is actually helpful.)
