FWIW (not much, since our Mac user base is small and we're in no rush to 
upgrade to Tcl/Tk 8.6), we're still on 10.3, mostly for lacking 
time/reason to upgrade.  But we're also still on Tcl/Tk 8.4.x (and still 
using separate tile and tkpng), so 8.6 not being compatible isn't likely 
to affect us for quite a while.

We tend to lag a a fair bit in moving to new Tcl/Tk minor versions in part 
to ensure one of our products (which is a binary package for Tcl) is still 
usable (stubs-compatible) by customers with older Tcl/Tk versions.  Might 
be different if the stubs mechanism had a way to build against a newer 
version of Tcl/Tk but target an older version (e.g., #define what version 
you want to target, and have stub APIs of later versions hidden from the 
compiler by #if/#endif wrappers so you get an error compiling your package 
if you try to use an API that didn't exist yet in the target version). 
But that's a big digression from the topic at hand.
