Another hint, not mentioned yet, is to click the rotation point twice.
This opens the rotate window directly.

So the idea is:
1) When you don't know the angle, but have two references, use the described way. Then the unknown angle is set in the rotate window, which can be directly confirmed to execute the rotation.

2) When you know the rotation angle, click the rotation center twice, then the rotate window opens to enter the rotation angle.

For both methods applies, that the options Delete/Keep/Multiple and Attributes/Layers can be set before executing the rotation. This is probably not much more effort than your proposal.
