In this case, with diamonds being displayed instead of escape sequences.
But that also applies to anything, so there is nothing to define here.

We should never change behavior in a way that makes a previously
comfortable user become uncomfortable.  Especially when the procedure to
undo the effects of the change is so convoluted that it necessitates a
long thread on emacs-devel.

I don't see why you have to conflate clearly unreasonable "comfort" with
reasonable behavior, such as letting the Linux console display
undisplayable characters as diamonds.
