Somewhere on this planet, Ol' Musky is reading this, and is thinking, "soon."

"It’s looking more encouraging that water ice could be available at depths shallow enough that could be used as resources for human missions to Mars,"

Large deposits of water within a few feet of the surface sounds ideal for what SpaceX intend with ISRU (In Situ Resource Extraction). Only question is whether the boring machines they will use to extract thousands of tonnes of water for propellant will leave tunnels suitable for habitation. Reminds a little of the Mars icehouse concept only constructed underground.

It reminds me of Hoth. Incidentally 3-6 feet below ground is a better blasted and strip mined kind of project. This doesn't take boring machines.

If the water ice is exposed to the low atmospheric pressure, without a few feet of pressure over it, will it sublimate?

It will but if they work fast it should be minimal. Its not like dry ice boiling. More like ice penitents in the Atacama desert.

Better in my view to bore past shallow ice, leaving it in place as radiation shielding for deeper galleries. Twofer, excavate all the water you need from deep deposits, leaving potential habitable areas underground with composite regolith/water radiation shielding.

The water ice likely has glacially ground and loose soil and rock on top which is not very stable. Use that expensive fuel to bore holes in solid rock for habitation. Incidentally we will live like Hobbits on Mars.

I'm an eager supporter of Mars missions and terraforming. Building on top of these important resources also means your "First Dwelling on Mars Museum" may one day be in a swamp, or even a large lake after we warm the place up! Take that into account.

If we manage to get the atmosphere back up to temp I think we can probably relocate any museum pieces to high ground too.

Any place on the surface of mars is going to get washed away whether it is on high ground or not. Suddenly adding lubrication to the entire bone dry surface of mars is going to make the entire planet mudslide city for decades upon decades even with plants and it would be worse in the time between first rains and wide spread ground cover. Well I guess you could move things up to the top of Olympus Mons but that is about the only place high enough to get out of the danger of rain.

True, just won't be in the same spot. Of course with all the mudslides maybe nothing will be in the same spot.
