As an outside observer - but with an interest in both weak-signal working and band-planning - I have to disagree.

The only way to assess the interference issue rigorously is to include it fully in the formal experimental program. Relegating the interference issue to "the local level" will exclude it from the big picture. Likewise, restricting the evaluation of weak-signal interference to TAPR's nominees within the program is a bad move, both technically and politically.

That isn't the point: the point is to generate and publish a complete record of the work, that can be analysed to extract general trends from a collection of localized data.

The experiments are not complete until they are reported; and they are not reported until they are published and shared with everybody. The "people... working on their experiments" of whom you speak are of course the participants; what about the non-participants who might be affected?

The concern of weak-signal operators is not really about interference from this limited test: it is about the potential for much more severe interference from multiple sources if SS becomes widespread. This test may be the only opportunity to collect data under controlled conditions, and there is no way to do that without public access to the participants' logs.

Amamteur bands have to carry the traffic of many diverse interests, each of which has equal rights. I support the SS experiments (which will surely come to this country too) but at present TAPR does not seem to be giving sufficient recognition to the effects of its own particular enthusiasms upon other users.
