I, too, have an overdeveloped appreciation of the elegance of simplicity and minimalism in the design and construction of rolling stock in general, race vehicles in particular. Space constraints and fabrication limitations drove my RPV choice. Flare and NPT connections are very well established as reliable. I wouldn't worry about a few extra of them. And if I can't afford a few more fittings, I can't afford a few fittings in the first place. But it is cool to see installations where the necessary parts and attachments are there, and unnecessary ones are not.
