I disagree.

For anything which is *documented* as "undefined" (even when we mean
"unspecified") we should feel free to change whenever we think the
benefits outweigh the costs, without any recourse to a deprecation

Fo anything which is *undocumented* (but that people have come to rely
on), we should not change without a deprecation cycle (short of a
security vulnerability, anyway).
