There was no reasonable real-world code examples taken from

underscores in numbers.
I recall dozens of real world examples that came up during the
discussion, and have written very numerous such examples in code of my
own. This is something that directly affects readability in code I
write almost every day, and is a clear and obvious win.
I taught examples *today* where I would have badly liked to have
underscore separators, and it was obvious to me and students that
awkwardness. Writing, e.g. `range(int(1e7))` feel contrives (but
usually the way I do it). Writing `range(10000000)` is nearly
impossible to parse visually. In contrast, writing
`range(10_000_000)` will be immediately clear and obvious.
None of those things can be said of SI units as Python literals.
Hu? None of those things? I do think you exaggerate quite a lot here.
If your real-world example works for underscores, it works for SI units
and scales as well.
I for one don't have usage of either, so having such a distance to the
subject at hand, I don't see this as a compelling argument against/for
his proposal.
