Not the ideal solution, but you can always use pandoc to convert org to html, or even markdown and configure the html generation from there.

Both html and markdown miss various org-specific features, like code fragments, drawers (imagine that one could want them to be able top open and close on click), task states, etc.

A general-purpose markup language like XML would be an ideal intermediate export format; XSLT can basically emit anything.

For drawers you could use https://developer.mozilla.org/en-US/docs/Web/HTML/Element/de... but yeah in general I agree
