Right, the client works as designed.
And the design is right according to academic principles, or according to 
'true religion'.

But there is a real world, and the troubles that esp. new users have, proof 
that the design is an aberration. You need to think big, Ced!

There are certain advantages that backward compatibility has
- fix bugs only in one location/version, instead of all versions
- use the latest client and take advantage from all bugfixes applied so far.
- and maybe the largest one, esp in once you run Tryton in a larger 
organization: have one client and be able to test / try various 
Tryton/GNUHealth versions. 
Useful e.g. for testing release upgrades. I know, someone (Nicolas?) proposed 
to tweak/script some way around it, but this is not user friendly.

I agree that a backward compatibility to ancient releases is not a good 
way...see A20 gate!

Successful companies and projects have one thing  in common: They listen to 
the needs of their customers / users. 

Maybe we make a poll for this?

Anyway, have a quiet and peaceful x-mas!
