The problem is not hull(), but implicit union. Hull only needs the
points in the input mesh(es). Applying [implicit] union() before
applying hull() to the result is like unknowingly driving with the hand
brake engaged. You perform a potentially costly computation (union())
only to immediately throw away the result.
One idea would be to provide an option to switch off implicit union, and
such issues will go away.
