Description

The default is currently true however, after discussion we're going to change the default to false. The basis or this change is the following:

While looking over some code in MyFaces I noticed in Faces 4.0 we have the following ELResolver:

https://github.com/apache/myfaces/blob/main/impl/src/main/java/org/apache/myfaces/el/resolver/LambdaBeanELResolver.java

This resolver is added to the resolver list here: https://github.com/apache/myfaces/blob/main/impl/src/main/java/org/apache/myfaces/el/DefaultELResolverBuilder.java#L154

Reading over the specification: https://jakarta.ee/specifications/faces/4.0/jakarta-faces-4.0.html#a2966 I wanted to 
start a discussion on the following point in the specification:

"These actual ELResolver instances must be added. It is not compliant to simply add other resolvers that preserve these semantics."
