Now that single roads have the option for a U-Turn at junctions, would it make sense in some cases to un-divide roads, at least at intersections? The goal is to eliminate erroneous "roads are too far apart" problems caused by U-turns too far away from the street junction.

Be sure to not delete any main street segments as addresses will be removed!
Take both sides, change to 2-way, disconnect from opposite ends of a section, then junction together in the middle.

I made a little video of this process. Watch it in fullscreen or at least 720p to see details. No cursor capture was working, sorry.

I have also verified that this process works even when the two sides of the split road have different names.

Aw, man. Stop it. I'm about to sob with happiness reading such things!
That's the exact way to get perfectly straight streets! (No mucking with the junction after of course.)

That is one potential downside. Depending on the segments, this may be negligible.

An editor who came and saw two divided roads meeting each other in which a previous editor added every single right and left turn lane might have made a good call to dramatically simplify, IMO.

It also, no matter what you do, destroys all accumulated turn timing as well simply because the segment IDs of the newly merged segment will be different. Fortunately that information gets built back up rather quickly.
