I've actual considered breaking them up even further.

+1 on that wording, I'll commit when I am next able to. Do see already
how I partially adapted for Cardoe's requests.

I'd propose the following variant:
A minimum set of depreciated checksums shall be maintained only to
support old package manager versions where needed by historically used
- New package manager versions should NOT use depreciated checksums in
  Manifests when newer checksums are available.
- New trees with that have never used the depreciated checksums may omit
  them for reasons of size, but are still strongly suggested to include
- Removal of depreciated checksums shall happen after no less than 18
  months or one major Portage version cycle, whichever is greater.

I'm not editing these into the checksum GLEP right now, as I'm sitting
in the food court at the airport, with my flight boarding shortly.
Most probably will be committed from my hotel room tomorrow night in

Signing off now, from an airport with bizarre wireless:
More than 45% of connections fail to start, but when they do, they're
good for more than 20Mbit. That's after you deal with the their broken
DNS in the auth mechanism (I'm probably the only person with working
wireless right now, so it's all the bandwidth to myself).
