Are they really needed? Don't we generally try to use automatic
dependencies when possible?

We also have plenty of packages without any choice, for example:

ifeq ($(BR2_PACKAGE_GNUTLS),y)
LIBNICE_CONF_OPTS += --with-crypto-library=gnutls
LIBNICE_DEPENDENCIES += gnutls
else
LIBNICE_CONF_OPTS += \
        --with-crypto-library=openssl \
        --with-openssl=$(STAGING_DIR)/usr
LIBNICE_DEPENDENCIES += openssl
endif

ifeq ($(BR2_PACKAGE_GNUTLS),y)
MSMTP_CONF_OPTS += --with-tls=gnutls
MSMTP_DEPENDENCIES += gnutls
else ifeq ($(BR2_PACKAGE_OPENSSL),y)
MSMTP_CONF_OPTS += --with-tls=openssl
MSMTP_DEPENDENCIES += openssl
else
MSMTP_CONF_OPTS += --with-tls=no
endif

etc, etc.
