Snapshot vs history log are not a comparable features. A snapshot is just that. More used for a varient for making a key image to try different processes on.
A history list of actions you made is a path to go back is a documented workflow. I think any well fine tuned image can benefit from such a history, LCC files composite files, any and all really.
I too fully agree, and I'm a bit surprised myself :-)
If you think about it, The brushes came after LR. The BW came after LR. the forsaken Catalog came after LR. Perhaps he is surprised to see they missed this adaptation. Or any top level developer as we place C1 and LR to miss usch a feature.
The "snapshot" in general is OK in theory, but not what happens in real life most of the time. I have yet to see a regular workflow with that feature being used in raw. Excxept from complex files in Photoshop; yes this is a handy feature. During a raw developing of a image, you work like a painter, a little here, a little there and this and that......You go along in a stride. THEN, you realize this looks great, but..."What did I do?" well, say goodbye or good luck trying to replicate. Hence the history log.
I think C1 stands strongly on its own as a developer. I have no doubt that most whoever uses C1 now would still use C1 as there primary raw dev without all the features they adopted from ACRaw/LR. What were they doing all this time before C1 had the feature? Too bad they went the route they did.
Even now, I still prefer making brush/layer edits in LR. The interface is much more visually intuitive. As visual artists, it is key. Much rather make the best RAW conversion possible in C1!..... then do all else in LR.
