So for what it's worth, Gecko implemented the current behavior of 
creating the stylesheet immediately as soon as we know the <link> is 
linking to a stylesheet in 
https://bugzilla.mozilla.org/show_bug.cgi?id=107567

One of the considerations there was in fact allowing pages to change 
disabled state without having to wait for the sheet to load.  That 
includes things like selection of alternate stylesheet sets working 
correctly even if not all the alternate sheets have finished loading and 
so forth...
