Fedora Wants to Drop UEFI Boot Support on MBR

Support for UEFI on MBR was originally added in blivet#764 to accommodate cloud image use cases, such as AWS, which at the time did not support UEFI booting on GPT disks. These constraints no longer apply to modern cloud platforms, making MBR-based UEFI setups unnecessary for current Fedora deployments.

Exactly. MBR is pretty much not used at this point except on legacy hardware where EFI is not supported. As mentioned, it's also unreliable in this particular combo.

Removing this does two things:

Ensures the most reliable way of installing is enforced by default
Removed untested and entangled bits of code that allows this to work (though the volume of code removed won't be huge)

Now that's just weird.
