How so? How is that different from a TEXTAREA compared to an
INPUT[type=file][accept="text/plain"]? I haven't heard anyone complain
TEXTAREA's are an intrusion of the author into user space, yet it's
clearly expressing the desire of the author to prefer content written on
the spot rather than picked from the file system.

Agreed. Nothing in the spec prevents UAs from providing as many options as
there see fit, including but not limited to access to the camera from a
regular filesystem picker, access to the picture gallery from the camera
UI, etc.

That's not necessarily true. The real reason authors ask for these
features are to improve the user's experience by making sure the operating
system's UI matches the application's context and the user's intent.

Consider the following scenarios:

1. John wants to sell furniture he owns online. He previously took
pictures with his camera and uploads them as required. He then realizes he
forgot to take a picture of the kitchen table. He just switches to the
camera mode of the file picker and snatches a picture. Here,
accept="image/*" makes perfect sense.

2. Anna is hiking at sunset. The scenery is beautiful and she wants to
share it with her family. She navigates to her preferred camera web app
and snatches a picture. Here, capture=camera makes perfect sense.

Best,
