I disagree with you. The partition type represents what kind of
style it uses, and to read a filesystem is depend on it. If you want
to have GRUB ignore the partition type, you must specify the slice
style explicitly. That is not what we want to do.
In addition, I assume that he used 63 instead of 83 because he
thought 83 would be for "Linux" partitions, but that is completely
wrong. 83 means just that the partition is ext2fs and DOS-style
partition is used. Ext2fs has the owner field, so we never need to
assume that ext2fs is only Linux's filesystem.

If we use 63 for Hurd, then how can we distinguish between DOS-style
partition and BSD-style partition? I'd like to reserve 63 until we
will really need to use a new partition type, for example, when GNU
filesystem that Thomas suggested will be implemented. If you need to
probe a Hurd partition automatically, it is enough to add the owner
field support into GRUB.
