Agreed with Icarus. ATPL is the requirement for command >5700kg, so makes perfect sense to require a check in a transport category aeroplane. After all it's the whole reason for needing the licence!
Another hoop to jump through but a practical one. As said, make it part of recurrent training/command base or proficiency check for FOs chasing a command from holding only a CPL. Particularly given regionals nowadays whereby less experienced FOs are being considered for commands.
