MarsSeed [1] filed a deletion request for mingw-w64-poco [2]: Unused library pkg from 2019. Former maintainer disowned it in 2022-04. Nothing depends on it.
(Even Arch extra/poco has only 1 downstream consumer.) [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/mingw-w64-poco/
