The old behaviour was buggy: sftp's -b uses ssh's BatchMode config
option. From ssh_config(5):

I.e. a sftp client in batch mode shouldn't require any interaction to
function. This stops it from blocking or otherwise misbehaving in
scripts.

If your users need scripted transfers, they can try:

sftp user@host < batchfile

-d
