If the last stragglers holding it back fear that it is *too* minimal, maybe now is the time to carefully try to find something to put it over the top for those in doubt. Max-min has not reached a consensus, but it seems to at least gotten agreement that aside from some bikeshedding, it all belongs in classes i.e. there is nothing which needs to be removed/substantially changed.
Agreed, but we need to me really careful to not slip into controversy mode about additional features. If that happens, it isn't clear that the recovery would be back to baseline max-min classes. It could go back to no class declarations at all.

There still seems to be some room on the syntax - private keyword for example, but overall seems pretty accepted. That makes it pretty solid ground, because adding it to classes would mostly be another piece of sugar to help bring the common parts together. Private names are a really great building block, but using private names in classes is going to be a really major use case for them, so I think it would be a pretty short leap to bring them together.
I think we need private outside of class declarations to cover all of the use cases (including those that aren't tied to classes).
I'd also be happy with private as a ClassElement that is lexically scoped to a ClassBody.
However, when we add private as a ClassElement we have crossed the line to having things other PropertyMethodDefinition in ClassBody. If this opens the flood gates for every over possible addition we will be back in the swamp.
We just need to be really careful to not get lost as we work toward final consensus on class definitions
