Comment (by dmsnell):

 I've proposed a patch which is permissive here. Core code may be used to
 more restrictions, but all of these are allowed in the browser and appear
 after requesting the `dataset` for an element. Is there a good reason to
 reject such valid data attributes, even if they are somewhat obscure?

 If there's one imaginable objection it would be to prevent storing data
 attributes named things like `data-no-<img-"tag"-in-here`. This is because
 such code might trip up weaker parsers down the line. However, this would
 or should be caught higher up than in `wp_kses_attr_check()` and so I
 think it's fine here not having that additional restriction.
