You need to organise your features in a way that these are not a problem. Need different dependencies - load both. Need a different schema - write both versions, drop old later. Need new services/APIs - feature flip only the user-visible one.

The flags are really useful for things like enabling just a fraction of traffic, or ensuring you can switch a feature off much quicker than a full deploy would take.

Everyone laughs when I say this but pull up a thesaurus. When you change the semantics of a thing, you have to change names to have old+new live at the same time. Don’t trust your mastery of English (especially if it’s your second language). There’s a synonym out there that describes the new behavior as well or even better.
