No, I think I stated pretty clearly that I have no practical experience
printing gum (yet). It was just a mental exercise to see what might happen
in a (theoretical) gum process that was repeatable and predictable (ha!).
For me it's just the foundation of understanding that I will work from when
I start to explore printing for real. I make no claims that it "proves"
anything. I'd love to see others' experimental results, and will certainly
share mine when I start doing some printing.

Perhaps you're right, but even if the later steps are somewhat
unpredictable, it couldn't hurt to start off on the right foot. Maybe this
is more applicable to something other than gum, or maybe it's useless for
alt process entirely; I don't know.
