[Agda] any known proof of ⊥ that does not syntactically use ∞ ?

Hi Vlad,

All known issues with sized types being able to prove false should be
listed here:
https://github.com/agda/agda/issues?q=is%3Aissue+is%3Aopen+label%3Afalse+label%3Asized-types.
>From those, the only one that does not immediately seem to involve infinity
is https://github.com/agda/agda/issues/4483, but it seems to me the issue
is no longer valid on the current development version of Agda.
