Re: [csswg-drafts] [selectors-4] Issue 11: Introduce pseudo-class matching when user changed the value of an input (#1533)

> With `:placeholder-shown`, `:checked`, `:indeterminate`, etc. I'm not sure what's the appeal for this. But I think the bigger issue I have with this, is what the "default" state is.

There are cases when you want to mark/highlight the input fields that were modified since page load. While this is easy to do for checkboxes/radio buttons (e.g. `input[checked]:not(:checked) {...}` and `input:not([checked]):checked {...}`), there isn't such a "straightforward" solution in the case of text inputs, textareas or selects.

In the context of `:dirty`, "default" would mean the value the input field had when the page was loaded (it might be empty or not). It is a good point, however, that in the case of SPAs there should be a way to "mark" a new value as default.
