Hi, Hannes,

I appreciate the idea of a 'ping' to the group. I also appreciate that
everyone has their area of focus, and not all things brought to a WG
receive the attention that's needed to move them forward.

IETFers have discussed incentive systems to encourage people to read
things that 'need to be reviewed', but let's not discuss that here.

Until we have that or an alternative - in the absence of positive
feedback - items should not move forward in a WG based on silence as
implicit approval.

If there is an absence of positive community support - either explicit,
or implicit by the community's lack of interest and silence - IMO, the
best path forward is to *revert* an item to individual submission, even
if it's on the WG charter.

Joe
