So, back when we proposed that the sidr work was mature enough to spin
up this working group to focus more on deploying it and less on what
should go into the base specification. we figured this would be an
involved and somewhat perilous transformation.

    This deployment must be properly handled to avoid the division of
    the Internet into separate networks. Sidrops is responsible for
    encouraging deployment of theSIDR technologies while ensuring as secure
    of a global routing system, as possible, during the transition.

To my mind this includes addressing the question of how we collectively
use it and consensus on how the moving parts are expected  to work. If
we don't have a consensus reality, then how am I to expect that my
network and yours will operate on the same information in similar ways.
Inter-domain routing really is one of those places where the consensus
reality had better be the market dominate one.

In the current charter sidrops does not intend to produce standards
track documents, with IETF and working group consensus being output as
BCPs when the weight of demonstrating consensus is required.

 That is a challenge in the case of for example

https://datatracker.ietf.org/doc/draft-ietf-sidrops-aspa-verification/

And one that should probably be more explicitly included if we are
amending the charter. If we take on the protocol specification
maintenance here there absolutely we should require interoperable
implementation for standards advancement.

requirements text around interoperability testing is good, but it needs
be expanded a little to let us do the protocol maintenance, which we
generally would have ascribed to IDR under the original charter.

I hope the current AD will revist this.
