I don't believe it's ever been discussed formally, but I like [that section you linked to](https://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style/Capital_letters#Composition_titles) and what we've done in most pages matches it reasonably well, so I agree with you that we should link to it from the Capitalisation chapter.

For sub-sub-headings, the formatting doesn't make them stand out very well, so I think continuing the capitalisation rules helps to make it clearer that they are headings. Also it's more consistent and easier to specify if we say that all headings of any level follow the same rules.

What do others think?
