As promised, this PR adds a commit on top of#59106 to improve the BC layer. This approach didn't fit in a review comment :) /cc@chalasr

This PR leverages the new#[\Deprecated] attribute to decide if someeraseCredentials() method is to be called or not.

My target DX here is to save us all (the community) from having to adderase_credentials: false configuration in all our apps.

So, instead of having to opt-out from the deprecation using this config option, the opt-out is done by adding the attribute on the method:

Before:

publicfunctioneraseCredentials():void{}

After:

#[\Deprecated]publicfunctioneraseCredentials():void{}// If your eraseCredentials() method was used to empty a "password" property:publicfunction__serialize():array{$data = (array)$this;    unset($data["\0".self::class."\0password"]);return$data;}

This should provide a smoother upgrade path (and maker-bundle could be updated right-away).
