yes. we hold these discussions in the bugtracker, under the
bugreport, so that they are not lost.
once some options crystallise, they are recorded in the wiki page,
from which later the ISA Extension document is written
an evaluation and decision is made after which implementation and
documentation takes place.
iterations and refinements including reevaluations of prior decisions
occurs based on feedback and if that involves looking back in
unstructured mailing list discussions it means time is wasted.
