Opera is regularly nagged by rich text editor authors who would like
us to support window.find(). Since it seems to be a requested feature,
it would be nice to have a proper spec ;-)

I guess that one of the main use cases indeed is to be able to
highlight search hits inside a single frame (using the browser's
built-in search might highlight hits both in a rich text editor's UI
and the document you're editing, which would be confusing)..

Yes, it is a counter-argument that authors could write their own
implementation. However, it's non-trivial to write a good text find
implementation in JS - it needs to handle text wrapping, text that is
split across different text nodes or tags, HTML entities, soft
hyphens, BiDi and probably a lot of issues I'm not aware of. It's a
lot simpler to let the JS author hook into the UA's presumably
superior and better tested algorithm.
