it's not a difference of the kernel

it's the question if it *really* achieves anything for users to siwitch 
a default with restrictions because *known* rough edges - nobody 
supports the users which end in troubles and can throw away all the ext4 
Google hits in case of trouble

for radical changes you should not ask "is it possible" - better ask 
"has it really benefits beating the drawbacks and so is worth now"

if it ain't broken don't fix it!
is ext4 broken? no!

so why would you prefer to replace it *as default*?

corrupted data is the worst which can happen on a computer and god 
beware you realize breakage too late and your backups contain damaged 
data - do you really want that possible burden as default for people 
know clue how to deal with it? people who know can use BTRFS anyways!
