It would make LKMs a bit more painful. I'd say if it's ain't broken,
don't fix it. Also, there is different issue that not all the emuls
really would use all the functions provided by compat_file.c, so
it would perhaps bring a bit more unnecessary code into custom
kernels.

I'd really wish someone would write /dev/ksyms. It could even
support ELF only nowadays. That would make emulation LKMs _so_ much
easier to use. Any takers?
