While you certainly can take your own copy of MathJax as it is open source, the MathJax Consortium does maintain a CDN that many of its users point their pages at. You can refer to a fixed version of MathJax in order to control when to move to a new version and to test it on your own content before going live.

How many people really > run with JS disabled these days anyway? I totally agree. But something that applies to general websites doesn't necessarily apply to specifications. Some specifications are still written in pure ASCII text, just to provide long term achievement (not at W3C). And JavaScript seems to be one of the things that belong to this kind of category that might make it harder to provide long term achievement. I am not sure if the W3C has any preferences to this topic. However MathJax might be different, since the content does not necessarily rely on the JS library. It would be good to know what the W3C policy is. Obviously, we would have to use our own snapshot of MathJax so we can be sure that there are no breaking changes. It would make our lives easier and the specs prettier.
