The single-line-of-ancestry rule means it's not a prism.

If I understand it correctly, the idea is that merges happen this way:

upstream -> foo--0 -> foo--1 -> foo--2
etc.

Note that in the example, direct merges to tla--longterm.X.Y.0.1 happen 
only after tla--longterm.X.Y.0.0 has been merged into tla--devo--X.Y

Even if so, having a label to hang on this pattern is useful.
