It's the same sftp server code either way. A quick test with
internal-sftp and chrootdirectory shows it's there:
$ sftp -vv localhost
debug2: Remote version: 3
debug2: Server supports extension "posix-rename at openssh.com" revision 1
debug2: Server supports extension "statvfs at openssh.com" revision 2
debug2: Server supports extension "fstatvfs at openssh.com" revision 2
Under what conditions does it not work? The only scenario I can think
of is of you had sshd and sftp-server from different OpenSSH releases.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
