it doesn't; and yes, my only "insight" was that we should make this an
informal policy and bring everything into line... ok, i'll go through
libplasma later and do this..

this should cover video sources in general, not webcams only of course. what
i'd be looking for personally is the addition of Video or DigitalVideo or
some such to Solid::DeviceInterface::Type. even if no video cameras are
currently even seen by Solid, it would at least point to where this support
will be coming in.
i see that HAL currently doesn't know anything special about video cameras, at
least according to the spec which is unfortunate.
is the policy in Solid to only expose what HAL can provide?
would it make any sense to have a Solid::Video object before a backend
