I've never had any Darcs enthusiast initiate an explanation of the data
model, actually. It only ever emerges from discussion about how
behaviour foo is more desirable than behaviour bar.

Perhaps so. It's that discussion about behaviour which leaves me still
searching for what's so attractive.

“a change is a patch” is not as tangible as “a change is a change in
the state of the files themselves”. Patches to content aren't all I
care about when tracking a working tree under version control.

Yes, the latter especially is what is so intangible. (For someone who
can express exactly what the issue is, I find it odd that you would say
“that seems very strange to me” :-)
Leaving it to algorithmic inference to derive the very thing that I
depend on the VCS to track, and not just storing it directly in the
revision data, seems like missing the whole point.
