* Returns {@code true} if strict superficial validation is enabled.

This option is enabled by default and allows Dagger to detect and fail if an element that
* supports being annotated with a scope or qualifier annotation is annotated with any
* unresolvable annotation types. This option is considered "strict" because in most cases we must
* fail for any unresolvable annotation types, not just scopes and qualifiers. In particular, if
* an annotation type is not resolvable, we don't have enough information to tell if it's a scope
* or qualifier, so we must fail for all unresolvable annotations.
*
*
This option can be disabled to allow easier migration from the legacy behavior of Dagger
* (i.e. versions less than or equal to 2.40.5). However, we will remove this option in a future
* version of Dagger.
*
*
Warning:Disabling this option means that Dagger may miss a scope or qualifier on a binding,
* leading to a (wrong) unscoped binding or a (wrong) unqualified binding, respectively.
