Is mounting an SRM speed sensor off the front fork more aero than putting it on the rear chain stay ? In the first two photos above you can clearly see it mounted out there.
There are two potential reasons that immediately come to mind.
My (10 year old) Polar S720 speed sensor doesn't work on the chainstay. The aerial was directional, and would only work if it was mounted to something more-or-less vertical (or pointing to the S720?). It would work on the seatstay (slightly more vertical), but then it struggled with the distance. I don't know if current SRM suffers from this, but it might well be stuck in some mechanics mind that speed sensors work better on forks. SRM HR was Suunto, but I'm not sure about the speed sensor, so I can't confirm if it suffered like the Polar.
The second potential reason is that the pro teams regularly have to mount race specific transponders on the chainstays. Maybe they don't want to mess with that area.

Sometimes I wonder if things like this happen all the time in the real word. Engineers spend countless hours ringing out every watt saving , than along comes the avg user who mounts something on the bike and screws it all up. Guy spends $10k to save a few watts , than in 5 min after he gets it, Poof all gone.
That might very well happen. I regularly see triathletes ride 90% of the time on the bullhorns.
For road racing I'm kinda partial to normal brakes in normal locations. Sometimes you have to swap wheels quickly, and on multi-day events it's a benefit if your toolbag is smaller. The brakes also have to work much harder than in a TT. Maybe I should look for an old stock Venge or new S3.
