MarsSeed [1] filed a deletion request for blueprint-compiler-health [2]: No longer needed by AUR/gnome-health, which has been deleted and adopted into Arch extra repo under the name 'health'. [a]
So this package remained here as an obsolete, outdated duplicate of Arch/extra/blueprint-compiler. [b] [a]: https://archlinux.org/packages/?name=health [b]: https://archlinux.org/packages/?q=blueprint-compiler [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/blueprint-compiler-health/
