Yes.

No.  However, I notice another environment
variable documented in the pkg-config man page called PKG_CONFIG_LIBDIR which

"Replaces the default pkg-config search directory."

I haven't tried that (since for my needs I want pkg-config to fall back to
/usr/lib/pkgconfig/ if it cannot find what it needs in PKG_CONFIG_PATH), but
it sounds like PKG_CONFIG_LIBDIR (or that variable in combination with
PKG_CONFIG_PATH) might give you the absolutely clean result that you want.
