Mmm, it was put in for F14 or F15 and then rolled back out for BIOS computers because there were too many instances of BIOS firmware doing a face plant without its beloved MBR. Many such instances are worked around with the pmbr_boot flag (parted terminology) which is setting the active flag on the 0xEE entry in the MBR, which is what you get if you use the gpt flag when booting install media. Otherwise MBR is used for BIOS computers. For (U)EFI computers, GPT is always used, and other than edge cases and unknowns anaconda is handling this OK, as far as I know.
