There is a classic tradeoff here between top down organisation dictates giving consistency vs engineering independence giving flexibility.

Two organisations that I know of who favour the latter are Spotify and Netflix. It has benefits - different languages are good for different jobs and engineers like to be able to choose their tools.

It would be bad if this was taken too far, and something was written in a language only one person knows, but that problem already exists with the technical knowledge if something only has one mantainer.
