I want to add my voice to this. Yes, better add them into the same files,
as different methods.
Branches are a maintainance mess, don't go that way.

Good point.

Yes, all helper methods need to exist in both variants.
 - or the load method can find out which tags are there, but this is slightly
slower (depending on which tag it looks for first, which would have to change
when switching the native format) and possibly error-prone.

It's quite funny though - there are two approaches to this. The usual company/government
approach, which is to make a study and decide on a common format, then start hacking,
and there's the opensource approach: start hacking, see how it goes.  ;-)
I like the fact that both are happening though. Your code and experience will provide very
interesting input to the study and definition of the standard format.
