T4 ground crew very shirty when I tried to check in at FBD T-3.5h in May this year, going WT+. The woman behind the desk v nearly told me it was more than her jobsworth - mentioned twice that my checked bag 'might go astray' if checked more than T-3 (nothing like a threat, is there). Back through T4 in July, WT+ again, and the staff at the FBD said nowt when I handed in my bags at T-3.5.
