It is not hard.  What is hard is when you change behavior abruptly
between releases without a transition period in which you warn about
an upcoming change when that deprecated feature is used.  Ideally, it
would have logged this error for the 7.3 release, and disallowed it
for 7.4, something akin to the LIMIT transition.

I guess nobody realized how some popular applications used this
non-compliant feature before the change was implemented.  Perhaps we
learn from this experience and don't do this type of change again.
Perhaps not.
