It certainly must be decided on a case-by-case bases, evaluating the
impacts in each case. If (like in this case), the ruled-out code uses
what many consider bad style, and if the code contradicts with a new
desirable feature, then it seems acceptable to break that code. If
code is broken, there should be clear instructions for people affected
how to modify their code.

In other cases, it may be better to remove the restriction from the
documentation.
