[Agda] Is bottom initial without functional extensionality?

Hi,
If ⊥ is the prototypical empty type, is it possible in Agda to prove
from⊥uniq : ∀ {i} {A : Set i} (f g : ⊥ -> A) -> f ≡ g
(where ≡ is propositional equality) without assuming extra postulates
such as functional extensionality?
My instinct is to doubt it, but the emptiness of the domain gives me
pause...
