Indeed. At first, I'll expect this API will get broken on a regular basis. Then it will stabilize such that old modules can still be used in slightly more recent Emacsen. But I don't expect to ever aim for the same kind of backward compatibility we expect for Elisp packages. IOW, "backward compatibility with existing dynamic modules" will be desirable but not "top priority". > For instance, that kind of deep integration is very likely to be > a blocker for concurrent threads of execution in the core. The alternative (which currently looks more reasonable) is that the introduction of concurrency will simply break many/most existing dynamic modules. Stefan
