I think it is fine to make a security recommendation for general Web browsers, and I fully expect that the major-market-share browsers will follow that anyway, due to general market forces and a need to be considered as secure as the competition. 

However, I'll say again, "not all UAs are Web browsers", and CSS is supposed to accommodate other uses too. 

EPUB is another example that uses CSS, where content doesn't usually link to the Web (the devices might not even support network connections), but might have internal links to chapters with graphic indications of what chapters you've started. Why should they be expected to abide by that restriction when it doesn't make any sense to them?
