I think a real problem here is that people (especially English only) do not understand the actual complexity of most standard input controls. They really think it’s just “type letters”. The number of times I’ve seen people showing their “fully functional” editors that flat out do not work with IM[E]s, do not handle basic keyboard controls, do not handle pasting or search propErly never ceases to amaze me. That’s before consider breaking all the password or address auto fills, screen readers, non-keyboard text entry. Even if all you’re doing is “restyling” controls, how do you interact with people who have vision difficulties like colour blindness? You’re restyling overrides accessibility features that make controls visible. Seriously, you don’t get to say “web apps should be just as capable as normal apps”, and also say “I should break basic app functionality”
