Although those libraries would undoubtedly be tremendously useful, we
have no expectation to write/spec such libraries... perhaps they are
more in the domain of the WebAPI WG?

Some HTML-based widgets at least have shown themselves to be quite
functional without the need of such libraries. Vendors, of course,
would be free to support such libraries but at the risk of
incompatibility (and many already do in respect to file-IO, sockets,
compression, graphic manipulation, etc). How we will consolidate such
variations in programmatic functionality in the spec is still an open
