'EXCEPT' keyword broken in conditions?

[Qonabe]

Tested this very simple script

EVERY 20 TICKS DO
IF test_check HAS GT 0 * EXCEPT bee_cage
THEN
INPUT fluid:: FROM test_input
OUTPUT 1 fluid:: TO test_output
END
END

'test_check HAS GT 0 * EXCEPT bee_cage' seems to always resolve to TRUE, no matter which item is in test_check

The video has a code with a condition slightly different but both the code used in the video AND the code above have been tested with the same simple setup (visible in the video).

Can confirm at least in 1.21.1, BoolHas makes no meaningful use of except.

Marked as needs repro, so here's another.
Make two barrels a and b, Put sticks and oak planks in a.

EVERY 20 TICKS DO
--  IF a HAS EQ 0     -- ...equivalent...
    IF a HAS EQ 0 EXCEPT stick
    THEN
        INPUT 1 FROM a
        OUTPUT TO b
    END
END

Expectation: removing planks from a will cause sticks to start moving 1-by-1
Actual behavior: nothing will ever move because the effective clause is just IF a HAS EQ 0.

Real use case: automating brewing stands

    IF EACH hopper HAS EQ 0
        AND EACH brew HAS EQ 0 EXCEPT blaze_powder, potion, splash_potion, lingering_potion
    THEN
        -- Brewing is complete; remove outputs and queue more ingredients in the hopper

In my case, a workaround was AND EACH brew SLOT 3 HAS EQ 0
