In certain circumstances, for example when doing a chartered boat dive, this would be reasonable-- and in some cases expected, but you have to be reasonable too. If I decided to take these steps as a mandatory part of diving, I would only be able to do it once or twice a year. This would be unacceptable. Additionally, more dives, conducted safely, are going to contribute to making a generally more confident and consequently safer diver. Abstaining from diving for the sake of waiting for the perfect circumstances seems like a recipe for declining skills to me.
