I would add that one way to gently enforce the stack when the system is getting built from scratch is having a solid end-to-end "POC"/"skeleton"/whatever you want to call it built by a senior architect before the rest of the team is brought in. Sure this requires an "architect who codes" type person to be involved (which can get expensive), as opposed to some ivory tower powerpoint architect but is typically worth it.
