how should we supplement URLs with more info to improve UX?

Suppose I want to share a link that works well in a text browser like lynx, or in a GUI browser with domain-specific javascript enabled and the rest disabled, and images disabled.

How do you do that? There is no format specification for this. The best you can do is write a paragraph telling users how to visit the link.

So the question is, why don’t we create a superset of the URL specification to include variables that deshitifies the page being visited and includes warnings for various anti-features?
