1. Synchronizing on trivial properties (otherwise you couldn't use `public` anyway!) is an anti-pattern, as it's a too fine-grained unit of concurrency and invites race conditions.
2. Can't proxy without rewriting byte code, you mean.
3. Of course you can evolve, it's just a breaking ABI change so it requires a trivial code migration on the side of the callee. If the cost of that migration is too high, something else is wrong.
a trivial code migration on the side of the callee
If your library is used by multiple consumers, forcing all them to migrate is not trivial, no matter how simple the change is.
If your income comes from these customers, it is not a good idea to put every one of them in the situation of having to choose between updating their code or stoping being your customer.
