I think for packaging it's okay to "have" lots of things that individually "do" one thing.

The important part is that the user controls the entry points. It's more Unixy to allow someone to decode audio from one pipe to another than to only allow them to play a file to a speaker.

Consider that Debian "does" lots of things because it has a kernel, hardware abstractions, a userland, a package manager, and often a GUI and web browser. But it also "does" none of those because it's just a convenient and useful wrapper to publish all the other tools, which you can still call upon individually
