As a practical one, the latter sentence makes the philosophic insufficiently-specified... To be inclusive, the operation of the group must rely on use of tools that are known to be widely and easily usable, in the IETF context, by essentially anyone wishing to participate. That permits quite a bit of variation, but not infinite variation. Limiting the choices to tools that have an established track record in the IETF removes risk from the meeting activity. Obviously there need to be ways to add new tools, but let's separate those and class them as 'experiments'. In fact a missing bit of IETF procedural documentation is a listing of tools that have been found to be both usable and useful, and in what ways they've been useful.
