It's not just that double-clicking is virtually unknown in the browser; it's also that "double click = remove" is unheard of in interaction design. It should be pretty straightforward to design a more usable and accessible alternative for such a basic function. Patterns abound.

Double-clicking in a web context is extremely uncommon, so most users won't even think to do it. The uncommonness of double-clicking isn't strictly an accessibility issue. It's more of a usability issue. Single-clicking is definitely a convention in web contexts, and it's generally a bad idea to require users to do something that they're not used to doing, and that they probably won't even think to try to do.

But the inability to double-click with a keyboard is definitely an accessibility issue.

Usually it's best to stick with events triggered by focus (onfocus or
onblur) or single-click (onclick).
