Syslinux - Jun 2017 - 64bit feature in ext4

At the moment, Syslinux doesn't support the 64bit feature of EXT4 
(which is now set on by default).

Considering the following code, I am wondering whether such support can 
be added to Syslinux.


GRUB2 supports the 64bit feature of EXT4 since:

 2012-07-02:
 Experimental support for 64-bit
 
http://git.savannah.gnu.org/cgit/grub.git/commit/grub-core/fs/ext2.c?id073b57bb8e2d688f33198f97076d01cea4455d7f

Since then, there seem to be some additional improvements to the 
relevant code.

 Diff since _just-before_ ext4 64bit support was originally introduced 
in GRUB2 up until now:
 
http://git.savannah.gnu.org/cgit/grub.git/diff/grub-core/fs/ext2.c?id=54
e7dbbcb93b913514e3e9f8f29e6372ea34ff32&id2=2e57f28fc737b9f45d1fc7cbe4a3d
48b7123fe68 


Perhaps looking at these specific Diffs in GRUB2 would somehow 
contribute towards adding support to this 64bit feature in Syslinux?

TIA,
Ady.

PS:
Unfortunately, supporting this EXT4's 64bit feature is seen as 
"almost-critical" (or worse) by common users and by distro maintainers
of 
modern Linux distributions.

It can, and it should ... it is pretty much a super-high-priority issue.

The sanest way to do it is probably to parse the inode into an internal
64-bit format, making each field contiguous and extending the older
format to 64 bits.
