Yes, this is a really sane and valid point.
Actually I did not mentioned that one of the reasons that I thought about migrating is that the project uses bower for frontend dependency management but bower is now deprecated and outputs message:
...psst! While Bower is maintained, we recommend yarn and webpack for new front-end projects!*
Of course this is just the build tool and possibly can be replaced without rewriting the application:
