API design: fused function for `solve_for_update` and `update`

It seems that in solve_for_update, `getsol = true` is always necessary to obtain the pivot value to pass to the `update` call.

In that case, are there scenarios where `getsol = true` happens? It could be good to have a top-level updating function that takes the index and column to replace. The fact that `solve_for_update` takes either in separate methods is confusing
