<input type="number"> is famously really flawed and not worth using even if what you want is semantically a number and not just numeric:

Tables have a whole bunch of flaws, like not letting you turn an entire row or cell into a link. (Some things are semantically tabular data!)
<button disabled> doesn't trigger various DOM events, forcing you to use <button aria-disabled="true"> if you need them.
These are the ones that come to mind immediately. I wouldn't be surprised if there are others.
