No, it would not.

It would mean desupporting a wide range of existing hardware and some VM 
environments (even with QEMU/KVM, I found the SeaBIOS legacy BIOS to be much 
less quirky than the OVMF UEFI implementation, and other VM environments 
might not support UEFI at all, including older QEMU versions that may still 
be in use as hosts for modern Fedora guests). And for what gain?

I do not think switching from GRUB-EFI to systemd-boot as you propose would 
be of any benefit for UEFI users. (It would actually mean fewer features for 
no tangible benefit.) Hence, we are dealing with GRUB in both enviroments. 
So I do not see the maintenance burden of continued BIOS support, also 
considering that, in my experience, the environment that keeps causing 
problems is actually UEFI, not BIOS.

Fedora should still continue to support legacy BIOS boot.
