Steps to reproduce the issue

If your modul as a lot of options / parameters it is a mess to use it in the frontend.
if you use a template that is not ready for using it frontend editing looks bad.

Requested result

Have a option to optional fallback to the pre 3.4 stat that redirects to the backend instend of the frontend. But the default value is Frontend.

Actual result

Only frontend editing is available.

Additional comments

This is a RFC to get comments on the points above.

True is that with the release of 3.4 we change the behavior from redirect to the backend (3.3.6) to the real frontend editig (3.4.x) that has e.g. known possible issues on 3dparty templates (e.g. with styling BS2vsBS3 etc.).
