I actually strongly agree here. If dropdown menus are so bad, then it's up to the user-agent to fix that. Remember that they're not actually <dropdown> element

I actually strongly agree here. If dropdown menus are so bad, then it's up to the user-agent to fix that. Remember that they're not actually <dropdown> elements, they're <select> elements. If actions that require performing a <select> can be implemented with a much better different UI for mobile or touch, then user agents are free (and encouraged) to do so.
