I think that this is a very solid point, but perhaps the reasoning underlying this type of issue is somewhat more complex. For example, we run a what is now a v5 of our API as a bunch of microservices and have been running it as microservices since v4, about 4 years now. These are "children" of v3 - our monolith. The monolith is still alive and kicking in a much reduced state but the reason we cannot decom it has nothing to do with design or time or priorities - the monolith is sitting in a data centre and is the only regulatory permitted way (in our case) to access the mainframe. So, it sits there as a gatekeeper and will do so for the foreseeable future...
