Details

Semantics would be as follows: when a package has "enhances" dependencies, but none of the packages listed in "enhances" are installed, the package is considered unused (for the purposes of listing in pacman -Qt). Otherwise the package is considered used. "Enhances" dependencies may not block removal of enhanced packages; pacman may warn about "enhancing" packages becoming orphaned when an "enhanced" package is removed.

The primary use case for this would be debug packages (which currently use "requires", whose semantics is quite unsuited for this purpose), but I'm confident it can find other uses as well.

Can you give a concrete example here? I don't understand any benefit of your proposal.

The explication look like just optdeps do now, enhance using optional dependencies.

Please upgrade and give explications why optdepend and enhance are differents

I don't see a use case for this feature as the handling of debug-symbols-as-a-package is an official makepkg feature now.
Pacman's own pacman-debug package relies on "depends=(pacman)", and not, as stated by OP on "requires", which incidentally, I can't find in `man PKGBUILD`. I don't understand the difference, though, as there is a good tool to remove all packages that depend on a package, which is pacman -Rc.

Unless there are any follow-ups, I'd like to suggest to WONTFIX this task until the end of the year.

I'm closing this due to lack of concrete example. Without more details we can not consider the request.
