As far as the FSDO and the insurance companies are concerned, it's just a CYA for you as well as them Even as stuffy as they may seem sometimes, it's not a bad idea to get to know the guys down at the local FSDO, they even smile and tell fishing stories if you take them to lunch. I'm starting the paper trail to get approval for a Continetal IO-240 installed on a Luscombe and the first thing I did was call the FSDO and invite them to chat about the possiblity after we had lunch. Probably saved me a few hours right off the git go. We also chatted about my Sonerai and a friends Bearhawk that are under construction. Orma, I should come up and see your plane one of these days.
