Doh.
solver_take_solution() modifies the task list (and I went to the trouble
of refactoring things to make it available to it), but I didn't then
re-solve with the modified task list.
Also, looking at this again, it looks like the solver places solutions
which remove a task at the end of of the solution list, so this should
be the default
(This matches the previous behaviour, where the default is to accept
dependencies i.e. if you try to remove a package required by other
packages, the default solution should be to cancel the removal)
Maybe we need more complex criteria to identify the default, but this
seems to work in my limited testing.
I've rebased and updated the topic/libsolv branch.
