Just a note on this bit:
It is abundantly clear that the OSI wants to move on, but I struggle to find constructive readings of the rush to ship a weasel-wordy version in which the issues that elicit most serious and evidence-based pushback from the community remain unaddressed.
And so, I don’t see how we can “get more endorsers” of a definition that is still partly up in the air.
I could perhaps support something like the leaner version proposed by @quaid here, which proposes to dispense with the two murkiest categories of data. As pointed out there, making sth stricter after a first loose version is never going to happen, so this is a now or never moment.
