Again: I'm not arguing what's best-practice. (I certainly concede that

Rather: I'm arguing against the "I'll remove any Theme that initializes
default options" statement.

"Bad code" is not inherently a reason to suspend Themes. And if we want to
make it a Guideline, that's great; but I see no reason not to follow our
established procedure for making such changes.
