Yes, this is intentional. Frame recognizers are visible to users and can (in theory) be extended via scripting:

```
(lldb) help frame recognizer
Commands for editing and viewing frame recognizers.

Syntax: frame recognizer [<sub-command-options>] 

The following subcommands are supported:

      add    -- Add a new frame recognizer.
      clear  -- Delete all frame recognizers.
      delete -- Delete an existing frame recognizer by id.
      info   -- Show which frame recognizer is applied a stack frame (if any).
      list   -- Show a list of active frame recognizers.

For more help on any particular subcommand, type 'help <command> <subcommand>'.
