For the same reason that the user is required to do an explicit commit
in a regular branch rather than bzr capturing every keystroke - not all
states are interesting, nor are all states sane, and finally, having
clear actions aids understanding what one is pushing and pulling.

For instance, an entire loom can be conflicted - each thread has to have
conflicts resolved separately after a loom level merge is done[this code
is not complete, but the data structures are there]. The states while
the loom is conflicted are not sane states for merging with other
people.
