It's unlikely they will get frozen before 0.9. We should probably start to use symbol versioning by 0.9 too, but I'm not sure how well this would work on ReactOS...
Is there a reason you're considering symvers rather than simply bumping the soname when ABI compatability is broken?
Is it a case of "well wine is huge, so we can't really expect people to install multiple versions"? I think that's the reasoning the libc people use, but as the bulk of Wine is effectively abi stable anyway thanks to the 'soft, I don't see it as being such a big deal.
