What's the latest status on Area2D not detecting StaticBody2D if not set to Monitorable?

Question

I just fixed a bug of Area2D not detecting StaticBody2D by setting the Area2D to monitorable. According to these 2 threads:

Area2D isn’t detecting Staticbody2D

I have a Button that is an Area2D and it activates a Switch that is a StaticBody2D that is a child node of the button. However, if the switch door enters the Area2D button with the collision layers set up the button does not detect it. The button can detect Characterbodies and Rigidbodies fine but not static bodies. I checked everything and I have no idea why this occurs.

Area2D Detecting Collisions with CharacterBody2D but not StaticBody2D

Godot Version 4.2.2 Stable Question I am creating a game in which projectiles need to “break” (spawn particles and queue_free) on collision with an enemy or surface. My projectiles have an Area2D as a child that detects collisions between enemies and surfaces. For some reason, the body_entered signal and body_shape_entered signal are never emitted when colliding with a StaticBody2D, but they are emitted when colliding with a CharacterBody2D. Using Godot’s built-in Change Type feature in the ed…

it’s a known bug. Then I looked at the issue on Github:

Area3D/Area2D doesn't detect static bodies if "Monitorable" is disabled

which states that back in 3.0 Areas were not supposed to detect StaticBodies, and that years later people are just treating it as something wonky and should be documented. My code still works as intended if the Area2D is set to monitorable but with no collision layers enabled, just masks. What I want to know is:

As of the current stable, are Areas supposed to be used to detect StaticBodies at all? Is the fact that the code works with monitorable on itself considered a bug, or just a normal workaround of a persistent bug?

What’s the alternative if any?

Should I switch to any alternative just in case a future update somehow “fixes” this by disabling Areas detecting StaticBodies altogether?

For my part, I just want to mention that every time I’ve tried to mark an area as non-monitorable, things haven’t worked as I think they should. I’ve always believed it was due to a lack of understanding on my part, and I still don’t understand it.
