This is great and everyone should be encouraged to follow your example!

No, you haven't missed anything except Unix ideology. That ideology is
telling us that one tool for one thing, and in very featurable mode.
That said, lingpiod is exclusively for GPIO ABI between kernel and
user space. For PWM you need to access the PWM ABI in a way how it's
represented by the Linux kernel. I believe there are plenty of
libraries more or less okayish for that purpose, but I never heard
about any official library and/or Python bindings for it.

Thierry, any suggestion here?
