I think you need to look at who is hit harder and if they can 
take the hit. Hard breakage does not hit newbies, only 
experienced developers. Mixed versions is very likely to add more 
confusion for newbies and also for more complex programs (in the 
future).

This is essentially political horse-trading because:

1. You sacrifice keeping things simple for newbies in favour of 
making it more palatable to experienced developers.

2. You a pushing additional complexity issues into the future by 
making it seem smoother now.

A technical solution to a political challenge, but there will be 
debt to be paid later on (newbies and future complexity).
