Thank you all for your reports. Since it seems this is generally the 
case with CentOS 7, does anyone also have access to RHEL 7 installations 
to verify if this is the case with these installations as well?

Probably none.  That file indicates which Linux device file corresponds 
to the (hdX) references in grub.cfg.  I'm not really sure it's even used
under grub2, since I don't see any of the (hdX) references in grub.cfg 
on the system I checked.

It's used. I can assure you of that, having had to fight one or two
systems back and bootable again....
