Good idea. You could also look at my last series of bumping wic and
reforking all the bootloader bits, enabling systemd-boot in the first
place.

That bootloader used to stick out because it was the only one to install
"from withing inside the target rootfs", as opposed to "from outside".

systemd itself is very likely to be installed there and the bootloader
used to be a part of that main package. But with >11 it has been split
out into its own package, so indeed even if the target runs systemd we
might not need to install that package. In fact we could probably even
use systemd-boot for a system using openrc or sysvinit.

I do not remember all the details.

But i do remember that i actually wanted to eventually move all
bootloaders to "inside" and maybe even drop support for "outside". That
would be to enable kernel updates in isar generated images.
And if one wanted boot loader updates the bootloaders would also have
to become part of the target install set.
