thank you very much for the elaboration, it was a fun read! I guess your 
expertice on this topic is unmatched by most other developers.

I think the long version of the risk documentation that you provided 
below would fit perfectly into README.Debian, though I agree that a 
TL/DR version would be nice to have as well. This should be accompanied 
by a short reference in the package description such as "Installing this 
package may impose some security risks that are discussed in detail in 
/usr/share/doc/steam-devices/README.Debian." The downside of this 
approach is, of course, that the documentation will only be available 
once the package is already installed.

But, to be honest, if you already share your computer hardware and 
access at the system console with a malicious user, there may be way 
more obvious ways to get attacked than through the steam-devices 
package, right?

Cheers,

  - Fabian
