I feel like "safely" sounds too fluffy and not reflective of the 
proposal.

     - How to force-drop support for old clients.
       or
     - How to depreciate support for old clients.

The second of these seems the most suitable.

Where can we find research on the impact?

With all due respect, doesn't Microsoft do stuff like this?  Is the 
impact so large that they require this level of action?

Is the proposal for 5 years in the past, pre this version, or can/will 
the cutoff be specified willy-nilly?

Ultimately, if this is the approach, and it is in the hands of each 
client operator, this could be good.  Though it would be great to hear 
from those who use previous versions to thwart limitations in "upgrades" 
to Firefox, such as the way media is streamed, amongst other things :)
