I'm a professional pilot and I do it. I haven't posted on here all that often but your tone has made me feel compelled to.
Whether you add "...for FIS/zone transit etc" on the end of your initial call up makes very little difference. You still have to pass your details to ATC, and you have made them aware that you require a service simply by calling up.
I doubt this little addition, whilst technically correct, is worth getting wound up over in the way that you are.
