Would it also make sense to add proxyBeanMethods=false to the @Configuration so that all beans in that class aren't proxied? This would also ensure this isn't reintroduced by accident.

If I recall correctly, proxyBeanMethods=false prevents the configuration class to be proxied, not the exposed beans.
Anyway, it makes sense to set that flag, since we have no direct method calls in SpringSecurityAutoConfiguration

I had the same assumption in the past :) until I've read the javadocs of the flag:

Specify whether @bean methods should get proxied in order to enforce bean lifecycle behavior, e.g. to return shared singleton bean instances even in case of direct @bean method calls in user code. This feature requires method interception, implemented through a runtime-generated CGLIB subclass which comes with limitations such as the configuration class and its methods not being allowed to declare final.

I read it as "configuration class is proxied so that bean methods will always return the same instance when called by other methods of the class". My understanding is that when, for example, you call annotatedViewAccessChecker() from another method inside the SpringSecurityAutoConfiguration class, it creates the instance at the first call, and subsequent invocation will return that one instead of a new instance how it would happen if the configuration class is not proxied.
So, SpringSecurityAutoConfiguration methods are proxied, but not their return value.
But I may be wrong. I'll double-check it

Good thing to double check! I only remember an old issue where boot also switched all their configuration to false by default, also to increase performance: spring-projects/spring-boot#9068

Before this is blocked: don't worry about it and do it later :)

I added the flag anyway, since it completely makes sense to avoid proxying in this case.
Thanks for pointing out 👍
