Given that both the CamelCase nGram and edgeNGram tokenFilter names (and tokenizers) are deprecated (in favour to lower_case_with_underscore) then why is PathHierarchyTokenizer left in both the preConfiguredTokenizers and tokenizers under both keys path_hierarchy and PathHierarchy without any exceptions or deprecation logging?

See CommonAnalysisModulePlugin.java for details.

Is this just an issue or is there any reasoning behind this decision? Shall I open a ticket?
