That'd be fine as well. I have fond memories of Tale of the Comet: http://www.drivethrurpg.com/product/17106/Tale-of-the-Comet-2e?it=1How would you feel if somebody wanted space ships and plasma rifles and light sabers and argued "If you want low tech dnd you got it in spades. Why can't have what I want too?" Do you see the arguments as parallel, or are they fundamentally different?
(Note that in principle I'm not opposed to low magic D&D, in fact I think D&D has become too high magic/fantasy. It's just when it leads to my character being...effectively...a follower of your character that I get nervous.)
A better problem would be pointing out that you don't need to make a brand new class just to have a high technology science fantasy D&D game or a low technology stone age D&D game. Instead, you modify the rules and, if needed, tweak the existing classes to match the variant type of game.
