The ext4 code can read and write ext3 filesystems without any
compatibility issues (i.e. none of the ext4-specific features are
enabled automatically) and have been doing so for all RHEL and SLES
users for the past several years via the CONFIG_EXT4_USE_FOR_EXT23
option (added in commit 24b58424 in 2009).  It looks like the same
for Ubuntu since early 2014 also.

The ext4-specific features either need to be enabled specifically
via tune2fs (if possible) or at mkfs time.

Cheers, Andreas
