Why not:
var mystyle = E('link', { rel: 'stylesheet', href: 'my.css', whenneeded: true });
document.body.appendChild(mystyle);
var myfetch = mystyle.fetch;
...
...where "E()" is some mechanism to easily create new elements (we need
one of those regardless), and "whenneeded" is some attribute that controls
the load policy (and in this case, tells it to not load yet, since I
presume that's what you're going to do next with the "myfetch" variable)?
("whenneeded" here is a placeholder. I don't expect to actually go with
that. I just used it because it's what I had proposed the last time this
came up.)
That seems like it'd be no more complicated, but would involve less new
API surface (not to mention fewer new ways to shoot yourself in the foot,
e.g. getting the 'fetch-as' value wrong), and wouldn't require us to come
up with a way to enumerate all the kinds of fetch in an API.
