Why do we still disable mke2fs 64bit support?

Why do we still disable mke2fs 64bit support?

[Marco Felsch]

Hi,

during a initial system-setup script the mke2fs tools complains about
the missing 64bit support:

8<----------------------------------------------------------------------
mke2fs 1.44.5 (15-Dec-2018)
64-bit filesystem support is not enabled.  The larger fields afforded by
this feature enable full-strength checksumming. Pass -O 64bit to rectify.
8<----------------------------------------------------------------------

Other build tools e.g. PTXdist or Buildroot don't modify the build-in
config. I know in the early days this feature break something but
shouldn't we (re-)think this decision?

Regards,
  Marco

I suppose as this point we just hope that there's not going to be still
more boards found in the wild where U-Boot is old enough to silently
corrupt on write or fail to find things on read.

And with my cranky U-Boot hat on, is there another new on-by-default
feature that'll prevent writing (or worse, reading) ext4 again?
