While the old name is explicit and aligned with the RFC, it's also very long, so with the mbedtls_ prefix prepended we get a 31-char prefix to each identifier, which quickly conflicts with our 80-column policy. The new name is shorter, it's what a lot of people use when speaking about that construction anyway, and hopefully should not introduce confusion at it seems unlikely that variants other than 20/1305 be standardised in the foreseeable future.
