You can ask your team about the flexibility of their architecture. How easy is the current setup such that new team members can be added, how piecemeal are the components and apis such that tasks can be delegated. It’s fair to be concerned that one or very few own your product implementation (and I speak as a developer). MERN stack is okay, but it can easily have ten other pieces that will make it a highly specialized stack. Things should be designed so you can rip out any of those letters. If you end up with a convoluted UI codebase, it will cost money and time to rip the R out. If you don’t get the right people to setup your database right, you won’t be able to pull the M out. The E and N are probably the hardest to mess up amongst the letters. Don’t add anymore invisible letters to the stack if you can avoid it (there’s a plethora of extra stuff a typical full stack dev now days is prepared to pull in if you search around).
