Yes, I'm not familiar with Rust, and I've been meaning to learn more there. The best response to my post thus far started off with a description of how Rust has successfully policed SemVer, and the issues they ran into: https://news.ycombinator.com/item?id=15676691#15677343. I'd greatly appreciate further pointers to how that community does things.

I just provided a trivial alternative that I found interesting. So much for your "tautology".

I do call it harder than it should be, by providing a simpler alternative.
It doesn't look like you disagree that a tuple is easier for the package manager to unpack than a string. You seem to be only saying that the difference isn't much. I've already agreed with that. So what are we arguing about?
I have a problem with the statement that "nothing interesting is trivial": it becomes license for hiding over-engineering. I'd rather say that "everything can be trivial". It's right about the same fraction of the time, and even when it's wrong it's an impetus to find better ways, rather than to be complacent.
I spend some time teaching programming, and it's amazing to me how often finding the right approach to teach something renders it almost trivial. See also Alan Kay's statement about the right perspective being worth 80 IQ points.
I have a problem with statements as general as "nothing interesting is trivial" (Or, indeed, "everything can be trivial".) They aren't concrete enough to actually support any serious amount of reasoning. You can end up anywhere you like depending on how you interpret them. This comment is about as much of such fluffy debate as I can handle without breaking out in hives.
Seriously, stop nit-picking wording in one sentence I quickly moved past in OP. It's mystifying to me why that's a better use of your time, rather than to elaborate on the "practical reasons" you so quickly skip past. I'm going to stop engaging here unless it is to discuss more substantive criticisms.
