I'm sure there are things they could do to better support the power-user engineer use case, but at the end of the day it's a self-hosted web app written in Python that has strong support for plugins. There should be very few things that an engineer couldn't figure out how to do between writing a plugin, tweaking source code, and just modifying files in place. And in the meantime I'm glad that it exists and apparently has enough traction to pay for itself.
