I agree, it is bothersome to have to add extra negative use flags when it could 
be ignored.

The gnutls flag doesn't have the meaning "I want gnutls". It has
the meaning "I prefer net-libs/gnutls as SSL/TLS provider". So with
USE="-ssl" the gnutls flag is a no-op, and neither the ebuild nor
the user should have to care about it.

Because having gnutls enabled and ssl disabled, if a package has both
flags, is nonsense? What is "I want gnutls but I don't want support
for SSL/TLS" supposed to do?

as I understand it ssl is intended as a generic use flag, of which
gnutls can be one of the providers. In the case of of app-crypt/gnupg
there are only two possible providers, gnutls, and ntbtls, of which only
one is available in tree, so gnutls is the only one, so the only one
relevant for Gentoo is gnutls, hence no use flag for it, either TLS is
enabled, or it is not.

in this scenario I don't see why "ssl -gnutls" would not be a valid
configuration as long as ssl is a generic use flag as it is presented to
be. It doesn't mean never install gnutls, but just not preferring it in
cases where there are other providers of ssl/tls, that the global
description already indicate.

NACK. This seems to imply that USE="-ssl gnutls" is not a valid
configuration? What if the user prefers gnutls and therefore has
globally enabled the gnutls flag, but -ssl for a single package?

How about "(needs USE=ssl to take effect)" instead?

[gentoo-dev] [PATCH] use.desc: Correct/clarify SSL/TLS-related flags

[Michał Górny]

Correct the description of SSL/TLS-related flags to match their modern
use. USE=ssl is a feature flag that enables support for SSL/TLS,
while USE=gnutls and USE=libressl are implementation toggling flags.

Unify the descriptions a bit. Make sure to mention both SSL and TLS
to avoid confusion. Inform about the necessity of enabling USE=ssl
in both implementation flags, and replace 'might' with 'if present'.
