I agree with your general sentiment.  It's hard enough to figure out
what's going on when there's only one layer involved but nearly
impossible when there are multiple layers interacting in non-obvious
ways.

In this case, though, the solution is simple: uninstall NetworkManager.
I had some WiFi problems and couldn't figure out what was happening so,
though I was then only vaguely aware of the /etc/network/interfaces
stuff, I got rid of NetworkManager and went back to basics, which was
pretty educational.  I intended to put NetworkManager back but never
have and now use some scripts which are an extension of these:

(I still have some WiFi problems, though different ones, and will
probably ask about them here at some point when I've done a bit
more experimenting.)
