I don't know if you make a power PC Mac build, but power PC Mac's can't upgrade past 10.5, and the early Intel Mac's like the PowerMac 1,1 can't upgrade past 10.7 officially. Unofficially it's possible by flashing the bios, using a special boot loader that translates 64-bit bios calls into the 32-bit bios the machine has, and a newer video card but that is totally unsupported by Apple. So no support for 10.5 will leave the PPC Mac folks out and 10.7 will leave the early Intel Mac's out unless they want to do like I did and load Linux on their Mac (which is a huge performance win).
We already dropped support for 10.5 long ago - in April 2012. No great disturbance in the Force was felt back then, not a single voice suddenly cried out in terror and was suddenly silenced. (with apologies to George Lucas)
Regarding the early Intel Mac's - I'm confused about what you wrote. If they can't upgrade *past* 10.7, then they can upgrade *to* 10.7, no?
32bit-only machines can't upgrade to 10.7, so these users will be locked out. It's less tragic than it sounds, though, as applications targeting 10.7 (including X2Go Client) should have no big trouble with running on 10.6, too.
Any machine supported by 10.7 should be upgradeable to 10.8, 10.9 and 10.10, though restrictions based on the graphics card may apply. I don't know the details on that.
By the way, even 10.7 is officially unsupported by Apple as of last year. This said, we can still support it, because it comes at "no additional costs" regarding compatibility.
