Idea: Safe subdomain for text-only content

[i-rme]

This way a link like this one: https://itty.bitty.site/#/data:text/html;charset=utf-8;bxze64,XQAAAAJBAAAAAAAAAAAqGgknZByHik/KTPT4HSNtN2h5G0ioByi51/j/XfI2TNaobPC0KdqzGEBb+tplhYhyKJ05lvFN3kKxiN/+IvwA

Could be converted to: https://safe.itty.bitty.site/#/data:text/html;charset=utf-8;bxze64,XQAAAAJBAAAAAAAAAAAqGgknZByHik/KTPT4HSNtN2h5G0ioByi51/j/XfI2TNaobPC0KdqzGEBb+tplhYhyKJ05lvFN3kKxiN/+IvwA

So the iframe becomes fully sandboxed (without "allow-scripts allow-forms allow-top-navigation allow-popups allow-modals").

So the user expects no javascript before opening the link.
