I can't speak to the implementation details but there must be a middle ground where you can set compatibility using 'set -N' or some similar approach to enable new behavior.

Scripting languages like Python, Ruby, Perl, etc., have dealt with upgrade many times. It has not always been pretty, but the alternative is stagnation.

And Oil has already done it. It needs to be faster, but that's an inevitability based on progress so far.
