<@UB2J9BQA0>, <@UKPS08ZGW>: <https://github.com/pantsbuild/pants/pull/9797> might look hairy, but the key thing is just that errors with traces get much more compact, and render only the Nodes with `user_facing_name`s: would appreciate a look today when you get a chance

Would it help to have a review from both? I started taking a look and then thought “That’s a lot of Rust - maybe I’ll ask Greg to take a look”.. hehe

the “is this trace useful for someone who would have `--print-exception-stacktrace`  enabled” bit is a widely applicable bikeshed i think

but the model will make it easier to add/remove `Nodes` from traces, so also fine to just land it and defer the tuning of traces.

if you want to just eyeball the python test changes, and then let <@UKPS08ZGW> look at the rest, that’d be fine too.

I'll take a look at this later today and focus on the rust parts
