ATT over BR/EDR uses a fixed PSM so separate discovery of this is not necessary. The core spec says: "The use of a fixed PSM allows rapid reconnection of the L2CAP channel for Attribute Protocol as a preliminary SDP query is not required." Based on git blame this item was added 5th Oct 2010, i.e. in the very early days of the LE specification. I suspect that there might have been some confusion regarding the ATT PSM back then. While this kind of PSM discovery it's not completely pointless, we don't do it for any other fixed PSM profiles either (e.g. A2DP & AVRCP) so I think it's better to spend time on more valuable tasks instead. I've now removed the ATT PSM related items from the TODO file (which btw could use much more cleanups in general).
