siblingpastry, Writing up some best-practice patterns for form controls, and I've assembled this list of native HTML controls that should never be used (because they're not universally supported, and/or their native UI has accessibility problems):
<input type="color">
<input type="date">
<input type="datetime">
<input type="datetime-local">
<input type="number">
<input type="time">
<input type="week">Any debate on those? Anything I've missed?
