I run a fiberglass boat with a keel guard and 90% of landings will have some way for me to launch without issue or damage. Sometimes I think docks just bring more non-fishing traffic and other issues to the landings. Maybe leave them out??? 
Biggest issue for me is I need to replace my front keel roller, boat is going to be difficult to get off the first time by myself without a dock. If they want to pull them back out after I launch and fix the trailer in the parking lot, fine with me, ha!
