I'm now maintaining modm for over 12 years and I've spent so much of my time fixing the CI, adapting to third-party API breaks, adding build system support, upgrading compilers. All of this is interesting the first time, but over time it becomes a drag. I've been wanting to refactor the I2C API for a long time, I want to add DMA by default to everything, I'd love to integrate our fibers into every driver, add tracing functionality. But I'm stuck preventing modm from just rotting away.
