Is modularity an unalloyed good? Modularity comes with tradeoffs that mean you end up with, well, a bunch of discrete modules rather than something that works cohesively. That's why systemd was adopted pretty much everywhere, ignoring the arbitrary modular boundaries results in a more useful tool.

Some analogs: modern filesystems like ZFS and BTRFS that combine volume management with the filesystem, every service that's consciously chosen to deploy a monolith instead of microservices, and so on, every deployment that chooses to statically link, etc.
