I think it's been the general air of contempt around this commit that has got to me. It's caused real users to experience issues (specifically those who keep images in a directory called Wordpress) and - most of them being non-technical and not following trac etc. - they'd have no clue why it's happening.

If this had just been mentioned beforehand, all the grief could have been avoided, instead they've got a PR gaff and a whirlwind backlash.

Unfortunately, the nature of some of the backlash, concentrating on tangent points and crying "revert, revert", seems to have meant that the proposed patches (which fix the bug if nothing else) are even less likely to be commited.
