One shouldn't seek to change a planet such as Mars into a replica of the Earth. It's actually fairly silly since the way things are done on Earth if done on Mars would have a partially green planet soon phasing out most species and green things etc.It would be good enough to just manufacture thick glass lock-blocks on Mars and construct glass domes and other structures inside which plants would be grown.
Allowing Martian ice and water to escape into the atmosphere is just a big, extravagant, profligate concept. Every day Martian water is being lost to space and there is no reason to expedite that.
When a surfeit of water exists somewhere and time perhaps from comets then actually terraforming some small planet experimentally would be worth the water.
Construction technology easily could learn to build vast solar energy collecting buildings to let human habitation and wildlife in other structures exist safely on Mars. It is just the reasonable way to go if designers want to have their oars in the water on Mars or Saturnian moons.
