MarsSeed [1] filed a deletion request for chromium-vaapi [2]: Unmaintained and unneeded package.
According to several comments made since April 2021, VA-API support got added by upstream release and it is enabled and working in Arch [extra] Chromium. Therefore this package no longer servers its former purpose. Safe to delete. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/chromium-vaapi/
