What's the goal?

If, during the lifetime of a binary string, data gets attached to it 
that makes it get upgraded, and later that data is detached, and the 
storage format is truly transparent, then when the string is used in a 
context that needs bytes, it should be handled properly (if not, let's 
fix that bug), either by downgrading, or by accessing the data and 
validating that the values are each < 256 (which downgrading does as a 
side effect).

If the goal is to prevent the cost of upgrading and downgrading, well, 
just fix the bug that attached the upgraded data... and the cost of 
doing so also vanishes.
