The HTML 4.01 specification explicitly and unambiguously warns against
using that syntax.

Most do. Some of them do support null end tags in HTML correctly and
then litter XHTML-as-text/html documents with displayed greater than
signs.

Besides, complying with, or at least extracting any sense from
Appendix C is hard. It is non-normative, mostly phrased to avoid
giving anything that looks like a requirement and gives contradictory
advice (e.g. advising against using processing instructions altogether
in C1 and then advising not to use stylesheets without them in C14).
