Totally understandable. I too do not have a paved area from my back door to the road. Again, my yard is sand with a bit of topsoil to hold what little grass we have. I have not had any problems.

I compete in triathlons so I have experienced every type of transition you could imagine. (Ok, except for gravel!) All of them take place at the beach. The longest transition I had to do was a run with our bikes for a quarter of a mile down the bike path. You could run on the paved path or run in the sand. Both were evil! I did not have any issue clipping in our out after that triathlon.

And I should note that I'm covered in salt water when I get on my bike. I do not race in socks, so the salt water is dripping down into my shoes and everything is covered in sand, dirt, leaves, sticks. That's part of triathlon.

Again, I do not think pro/elite/age group triathletes would compete in SpeedPlays if there were concerns or issues with the cleats.

There are other reasons to not try them, but cleat issues with dirt/sand just doesn't happen.
