The statement that Android needs to support an older mechanism for some time is too strong, as an Android version generally is an association between a user and a kernel. It's quite unusual to upgrade the kernel without updating the userland (although the opposite isn't necessarily true). Adding a configuration to the userland build to match it to the kernel should be sufficient to allow a flag day change.
