That is quite nice - ask user at install time whether to remove the disk manager.
However, after doing that it seems appropriate for a booting kernel to autodetect the presence or absence of the disk manager and behave accordingly.
Once the redhat installer has determined that there really is a disk manager, and that the user wants it that way, it can add the boot parameter hda=remap63.
I dislike autodetection. The word sounds so nice. But a synonym is guessing.
If kernel guessing is required it means that some interface is missing. Policy should be determined from userspace.
But of course, it is easy to add some heuristic code. I would prefer to keep such code out of the vanilla kernel, but a vendor might want it.
[And note that todays patch did not remove any DM detection. This discussion is 37 patch levels late.]
