I believe that such an implementation would not be SRFI 22 compliant.
Currently the SRFI says that

     scheme-script filename ...

will load the Scheme script in the file "filename".  If a system loads
the file "filename.o1" instead, then that is surely not conformant.

If you want scripts to be compilable, SRFI 22 has to provide for this
explicitly.
