Shouldn't GLEP 57 be included in this list (although it's only
informational)?

In case we accept 5.1., I suggest that we delegate it to the Portage
team to produce a list (which can also be empty) of the "maybe others"
files.

Right, that's the intention of it.

We should also consider including this in EAPI 0 retroactively, as
suggested by Zac in [1]. Look at the following sequence of events:

  2007-07-28  Portage 2.1.3 is released, preserving mtimes when
              merging (if release candidates are counted, then the
              date is even earlier [2]).

  2008-05-08  PMS allows that file modification times are discarded. [3]

I don't.
