The point your parent is making is that with mom, you can install one version of a package per project you’re working on, instead of one version on the system. Especially if you’re working on multiple projects or multiple versions of the same project, this is required.
It's definitely not used as often as in npm packages, but you can use =version after your package name to apt install a particular version, or apt pinning for more complex setups.
