touch support can already be feature detected #14

If the use case is determining whether to add touch event handlers to your application, there are existing feature detection techniques that can help.

If the use case is a web application that wants to know which screen to place a window that requires touch, screen.touchSupport could be useful?

Thanks for the link! Yes, both techniques have good use cases:

Feature detection: optimize the content for touch-enabled (or not) displays where the window happens to be open.
screen.touchSupport js introspection: Check the properties of multiple displays, place a window on the one with touch support (e.g. for conference rooms with big non-touch video screens and small touch-enabled controller screens)

I'll add this better use case to the explainer.

I believe the updated explainer addresses the desire to select screens by their properties, including touch support. Please let me know if the proposal's language could better explicitly describe that goal.
