Incomplete list of mistakes in the design of CSS

Why can't this be dealt with with CSS versioning/features where you can opt into your current-color and a lot of more substantive style behavior while leaving currentColor functional?

A lot of the behaviors should just have a toggle to turn them off. For example, there are many situations where margin collapsing is in the way and I keep wondering why there isn't simply a `margin-collapse: none`. It would also be nice to have something like `default-styles: none` that will remove all the default styling for h1/h2/etc. and em/strong/cite/etc. so I don't have to deal with browsers having differing defaults.

This already exists:

    *, ::before, ::after { all: unset }
