Code needs to get testing before it's put in the kernel.  How's that
supposed to happen if it's not made available outside the kernel tree
first?

Why does the kernel build system support building out of tree modules if no
one should do it?

Maybe an option to turn i2c algorithms on could do into the Library
Routines menu.  There are already options for things like the crc routines
here so they can be turned on if an out of tree driver needs them but
nothing in the kernel does.
