You can successfully use this approach only if you do not have external dependencies. If you use some library you have basically the same problem as multirepos. I worked in companies with monorepo and it work really well. Except all external dependencies were copied into monorepo, outdated and with unpatched security problems because no one ever updated them unless there was some functionality missing. Also there were some internal libraries for logging etc. which were worse than publicly available alternatives but it was easier to maintain them then use something standard.
