of course they are only after the pool, but if you are vocal enough and willing to compromise, you might be able to incorporate something really worthwhile into their actual design.
from the perspective of seeing similar types of projects get bandied around in my work environment, you are better off trying to incorporate the best aspect you can in the design rather than demanding an offset item that would cost more than the actual project itself!!! tweaking that wall to maximise reflection and still mitigate scour in front of the tea room if possible would be the go imo.
re: surfing over rocks from groynes - have you ever dived over a few different examples of "natural reef" in the metro that most of us regularly surf on, on a calm day? i can point out a couple of cheese graters around the state as well to check out that might change your perspective

or just stick to sand bars, no wait.. hitting one of those could also be an accident waiting to happen. maybe just go down to the cott pool and swim laps?
