Problem

Introducing fundamental behavioral changes like registering standalone figures #29855, GUI-native drawing elements #30516, or the data prototype may cause unforeseen side effects.

• ship experimental features and allow early adopters to try them out by opt-in
• if the flag is active by default, users have the chance to opt out if the feature breaks their work
