This technique was sort of possible before, but it would break if the player looked straight up or down, since it's not possible in that case to find the player's yaw based only on Alidade's Purification. However, the introduction of Theodolite Purification in Hexical 1.3.0 makes this fully possible, as that pattern gives the up vector of the player's head; with that, we have enough information to construct a coordinate space that rotates with the player's head. (This would also be useful for creating HUDs that stay at a constant position in the player's view.)
One interesting use case could be to use this macro along with Mediaworks' Macula and Hexical's Telepathy to implement a working GUI in Hex Casting.
The code for these macros/hexes (and many others) are available on GitHub.

Mouse Input
reference look, reference up, current look, current up → (x, y) | (null, null)
Given reference and current look/up directions, returns an x/y mouse position relative to the reference position.
The position (0, 0) is at the reference, x increases when yawing right, and y increases when pitching up. The coordinates range from -1 to 1, at -90 and 90 degrees from the reference respectively. If the mouse goes out of bounds in either axis, null is returned for both values.

}reference look, reference up, current look, current up → yaw, pitch
Given reference and current look/up directions, returns the current yaw and pitch relative to the reference.
All inputs should be unit vectors, and the returned values are in radians. Yaw increases right, and pitch increases down.
To get the pitch/yaw from the F3 screen, use (0, 0, 1) and (0, 1, 0) as the reference look and up vectors respectively.
