Agree 100% with Oblaas and Contacted - carry it if you NEED it, but why carry it if you don't? Even when it's busy in DXB you'll only get 2 turns at DESDI or BUBIN now that ATC have got to grips with the reduced landing separation... And it's no big deal to commit either... Just seems to me that some don't like the change of fuel policy but it works fine - same policy my last operator used!
And no-one's run out of gas there yet
