I would be happy with the text that was used in the xmpp charter:
Although not encouraged, non-backwards-compatible changes to the
basis specifications will be acceptable if the working group
determines that the changes are required to meet the group's
technical objectives and the group clearly documents the reasons
for making them.
This text still keeps the bar high for unnecessary changes, was already
vetted through an existing charter, and helped us through a similar
impasse when xmpp was chartered.
