There is some trouble in the ambiguity of what we mean by "modern" and
"large files". There are still a large number of users of ext4 where the
max file size is 16TB. Switching to a single large file per relation would
effectively cut the max table size in half for those users. How would a
user with say a 20TB table running on ext4 be impacted by this change?
