As the physical feel of an element can be considered a part of its style, we're proposing to extend CSS to allow assigning the tactile feedback style to web elements. According to our studies the most convenient and natural way to specify haptic feedback is CSS. We also considered implementing haptics for web using WAI-ARIA but came to the conclusion that haptics is not (just) an accessibility feature although it can be used for improving accessibility as well.

My initial impression is that most of this (aside from 'haptic-tap-strength') should be handled by the 'appearance' property, to get a UA-appropriate representation of a button, checkbox, etc.. That would also handle the :active state of the button, etc. automatically. The state of the checkbox or deciding if something is a link or not would be decided by the document language and DOM.
