As more features get moved into modules, inter-module connections imho becomes more important as for example ettr using dual_iso's calls with "extern WEAK_FUNC(ret_0) ...". But what if I want to do these things w/o touching the other module:
1. detect if a module is loaded at all?
2. get or set other module's config vars?
Are there existing code samples anywhere? If not, it'd be great if there would be a core framework for these, for example module_check_enabled("ettr") and module_set/get_config("ettr", "auto_ettr", "0").
