That sounds awful. How do you share any of your common logic? Do you have to write versions of your important routines once in each language, each with its own set of quirks and bugs?
It's bad enough in microservice land, where every time you want any shared code you have to extract it to a e.g. "utils" library and massage the versioning to get it in to the right apps.
End result: most people don't and you end up with many different little versions of your routines that do important things.
