Request #8163 has been rejected by ArchangeGabriel :
go-makepkg needs enhancements too (do not use date for VCS pkgver…). And go-makepkg-git is the right name.
What should be done: ask for go-makepkg-git to be orphaned, take maintainership of it, and change the PKGBUILD to be an enhancement of go-makepkg one.
Then ask for go-makepkg to be merged into go-makepkg-git.
