yes I am relying on .4ht files provided by tex4ht, tex4ht.sty is
loaded by lua4ht.sty in the case it wasn't loaded by calling script
(like `make4ht -lun -m draft filename`). So this means that you still
need to provide .4ht files in order to insert html tags.
But because lua4ht has full access to nodes created by luatex, some
interesting things are possible. I am exploring possibility of using
`mlist_to_hlist` callback to convert math nodes to mathml, because
mathml implementation in tex4ht depends on some tricks with dvi file
and I don't know whether these tricks are possible to emulate in node
callbacks. Other things which may be possible and which are not
supported with tex4ht is support for vertical skips and rules.
