I am with you on the practicalities of not being too quick off the mark to push the "wet" button, but is it not taken care of (at least under EU-OPS and its offspring) by the requirement of 1.490 b 5:
"on a wet or contaminated runway, the take-off mass must not exceed that permitted for a take-off on a dry runway
under the same conditions."
I appreciate that this may be a geographical issue!!
Have now actually thought about it, and of course even if the mass is the same the lower V1 results in a lower screen height in the accelerate-go case.
