It most certainly is.
The main motivation here is:
Distros know how to handle grub.cfg programmatically, as do most users.
I see it as an abstraction layer on top of u-boot with its environment
variables, boot commands and all the magic to find devicetree files or
kernels, providing a much more simplified interface.
As soon as grub has been launched, u-boot is history and nobody has to
care how it achieved its magic.

Example: The devicetree file is now loaded from sdcard by u-boot, and
then passed on to grub through the EFI interface. Grub in turn doesn't
have to care about choosing and loading that one.
