What would such a replacement look like though?

Some sort of system whereby you can read/write single-line commands as
if talking to a GPIO expander over a UART?

Would you access the GPIOs one by one, or would you perhaps map them
into a bitmap (maybe arbitrarily, up to 64-bits wide) and perform masked
operations on the bitmap?

I'm no fan of the sysfs GPIO interface, but it beats poking around at
registers behind the kernel's back.
