Doom 2016 – What’s Up With Screw Attack Looking Things on Map?

These icons crop up from time to time.

At first I thought they showed north, but there are maps with several of them. Then I thought maybe they were teleporters, but that doesn't seem to line up either

That is the symbol for power-ups, such as Quad Damage, Invulnerability, Haste, etc. They all seem to share the same map icon.
