My concern is not about what my flavor of kernel includes. It's about the size of the codebase, and whether the limited number of maintainers can keep up with the countless features being introduced.
Even the larger world outside the field is somewhat aware of the the looming complexity problem: https://www.theatlantic.com/technology/archive/2017/09/savin...
Basically on our current trajectory we will end up with something like the biosphere that can do stuff but too complex to fully understand --- but also probably well more fragile than that?
So the codebase is actually not growing as much as it could.
