When profiles are transferred, its delegated executor config is not cleared. Instead, the function switches its config to a new config:
LensProfiles.sol#L165-L177
This could potentially be dangerous as users are able to switch back to previous configs using changeDelegatedExecutorsConfig(). If a previous owner had added himself to previous configs, switching back to a previous config might potentially give the previous owner the ability to steal the profile, or execute malicious functions as a delegated executor.
Consider warning users about the danger of switching to previous configs in the documentation.
