Did you mean to refer to <https://issues.guix.gnu.org/22138> here
(‘Search paths of dependencies are not honored’)?

We do add SSL_CERT_DIR to guix even though guix it is only used through
guile+openssl (though we seem to forget to add it to many other
packages).  We sometimes add XDG_DATA_DIRS and XDG_CONFIG_DIRS to
‘leaf’ packages even though it is (usually) only used by some glib-
related things.

So aside from perhaps 22138, I don't see a problem here.  As long as
22138 isn't addressed, how else could Guix determine that some leaf
package needs TERMINFO_DIRS to be set?

Greetings,
Maxime.
