Not that I am for or against so much, rather that this is an issue that should have been handled years ago. Either make an exception and allow them a path to naturalize or don't and ensure their removal.
The path for DACA folks to become naturalized ... do they all want this? I know a couple (work with) that had DACA status. One is on the way to become a citizen (via Advance Parole with help from our legal group) and the other married a local. There are options. Easy? No. An immigration attorney can help. In the end, this is a Congressional failure. This should have been addressed, stay or go. President Trump has been left holding the Hot Potato when the timer went off.
I suspect that the great majority of DACA-eligible aliens would want to become either lawful permanent residents or citizens if they were able to. Prior to DACA that was meaningfully impossible for most. Even with DACA it's only possible for a relatively small subset of them.
Even with advance parole, which a DACA alien is only eligible for under certain circumstances (and which means they have to leave the country and risk being denied re-entry even though they may have advance parole), most of the bases for an immigrant visa (and thus an adjustment of status to lawful permanent resident) aren't available. The one that is is based on having an immediate relative who is a citizen. Except in some pretty unusual cases, that (for a DACA alien) would mean a spouse. So they'd have to qualify for advance parole, leave the country and return, and be married to a U.S. citizen.
If you don't mind my asking, regarding the first person whom you mention (whom you work with), what's their bases for an adjustment to status? You mentioned that the second one was married. Is that the case with the first one also? Otherwise, they'd have to have a parent who was a U.S. citizen or a child 21 or over who was a U.S. citizen. Considering the age limit on the (original) DACA program, the latter would mean that they had a child when they were fairly young. Most DACA aliens wouldn't be in that position.
That said, I would agree that this situation is a failure of Congress and of political / democratic processes in general. The state of our laws in this regard is... I'll just say not good. Something should have been done long ago to address the issue.
