MarsSeed [1] filed a deletion request for lib32-suitesparse [2]: This library is no longer needed by any other package.
(Was a non-mandatory dependency of lib32-gegl to accelerate some highly complex graphics transformations by lib32-gimp, which its consuming legacy scanner drivers don't actually do.) [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lib32-suitesparse/
