Blocking first party Javascript is a form of lunacy that is so illogical I can only shake my head. Let's say the site runs XSLT in Javascript. Now what? There's nothing that can be done and yet you would ask for further accommodation.

Here is why this is abusive: You can always restrict the subset of the web platform you demand to a subset that is arbitrarily difficult or even impossible to support. No matter how much accommodation is granted, it will be all for naught, because some guy out there goes even further with blocking things and starts blocking CSS. Next thing you know there's a guy who blocks HTML and you're expected to render out your website as a SVG with clickable links.
