I must admit being slightly confused, here.

If the goal is to enable more precise keywords in the future (such as
"scanner", or "front-camera"), there's little point in arguing about
making "camera" less specific. On the other hand if the keywords we're
using today are meant to be all encompassing, then fantasai is right and
capture should just be a boolean attribute that describes whether the file
should come from a live source (camera, camcorder, microphone) or the
filesystem. In this second scenario, the capture control type would be
exclusively defined by the accept attribute.

Maybe a note in the spec saying that this list of keyword can be extended
in the future would help clarify this.
