Just barely.  I imagine that if your doc includes instructions for JCL such as:
    //stepname EXEC PGM=AMATERSE,PARM=UNPACK
    //SYSUT1 DD DISP=bbb,DSN=your.input.dataset.name
    //    ...
And AMATERSE UPPACK is suddenly enhanced to allow a UNIX file as SYSUT1,
those instructions remain valid but become a restriction.  I wouldn't worry.

I consider it vanishingly unlikely that IBM will someday require that SYSUT1
be a UNIX file.

It should be an easy enhancement for IBM to make.  Today this works:
    //stepname EXEC PGM=AMATERSE,PARM=UNPACK
    //SYSUT1 DD UNIT=SYSALLDA,SPACE=(1,0)
    //       DD PATHOPTS=ORDONLY,
    //  PATH='your.input.UNIX.file'
    //    ...
