Speaking as sys-boot/syslinux maintainer, I would like to see it
included in the official installation documentation. However there are
some differences between grub{,2} and syslinux/extlinux that could
block universal adoption.
Installation:
Syslinux installs into a partition which means that /boot must be on
one of the supported filesystems. Currently these are btrfs, ext2/3/4
and vfat (ntfs support will come in the next release). Also this means
that /boot cannot reside on a logical partition. To my knowledge,
there are no plans to allow booting from LVM either.
Dual-booting:
Telling users to create GPT instead of MBR partitions could address
the logical partition issue, however this would make dual-booting
Windows difficult. And Windows has been observed to behave strangely
when its BCD is not on a partition which has the boot flag set. There
are workarounds but documenting them would increase the complexity of
the handbook.
EFI:
Syslinux does not boot on EFI yet. Not a big problem as UEFI will fall
back to BIOS mode but this can bite users on Apple hardware.
Xen:
Booting Xen generally works, but some specialties like Mini-OS aren't
supported and likely won't be in the near future.
tl;dr
Syslinux/extlinux can replace grub in many if not most cases. But for
a number of setups it is not well-suited. So a documented and stable
grub2 will still be needed.
