That's a decent start for a good commit message; although giving even
more details about which interfaces are candidates for moving (to make
it easier for future patches to know which of the two files to add to)
would be helpful.

Also, do you have any before/after comparisons, perhaps such as size of
the executables or of 'nm | wc' output, proving that the split makes an
obvious difference?
