Note that we're specifically talking about rebase, not other Git
operations. As I understand it from your descriptions and others
<URL:http://blog.experimentalworks.net/2009/03/merge-vs-rebase-a-deep-dive-into-the-mysteries-of-revision-control/>,
rebase makes the revisions *not there anymore* in the branch history.
Whether they're still in the repository somewhere isn't relevant to
this point: they're gone *from the branch*.

That's the significant difference I'm pointing out with a loom:
revisions never go away from the branch, but new ones get added.

What you call UI in this context, I call the data model. The data model
in rebase is that history, as modelled by the tool and presented to the
user, is altered. With a loom, that's not true.

I'm not sure how you distinguish; this looks perilously close to the
“no true Scotsman” fallacy, where no matter how much I learn, if my
opinions of what I've learned don't meet your expectations I'm still not
considered to have “grokked” it.

Exactly what am I supposed to grok, and what FUD am I currently subject
to?

I've never feared Git; either that, or I don't know what you mean.
