I'm including a changeset for this because it's technically breaking.

Let's say contract A inherits from OpenZeppelin's ERC4626 and overrode asset(). Then, after upgrading, the developer may not expect that now asset() is called. This is risky if (for example), the asset() performs a static call as it may introduce a way to execute read-only reentrancy.

I haven't come up with 1) an honest reason to insert a staticcall in the middle of asset() or 2) a way in which the contract will break after an upgrade.

Overall I think having the changelog entry should be enough
