AFAIK Apple's reason for this is similar to no longer providing headers for
OpenSSL [1] (or now actually BoringSSL): they cannot guarantee binary
compatibility of these libs beyond individual macOS releases (i.e. without
breaking old clients) and bad things happened [2] in the past for apps which
expected it would.

The common recommendation is: "Ship your macOS app bundled with the preferred
version of these libs."
