Well not really, no -- the additional *DEPENDs that are being proposed (or at least mentioned) for new EAPI will either remove atoms from COMMON_DEPEND/DEPEND/RDEPEND or will be used so tersely that a COMMON_DEPEND or other intermediate variable won't really be necessary for them. Besides, this isn't actually a -problem- as there's nothing which really requires one to use such helpers; ebuild writers just, well, can. :) -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iF4EAREIAAYFAlBZxZIACgkQ2ugaI38ACPDp4wD/atjvaOsi/ntDMB1Dj7lSAVmW 45qKz6+OO+H/+6eFeVIA/Rz0s7FiG6d2frboHXpYrDBzM1FZcU85AqZti34tR8+h =E78Z -----END PGP SIGNATURE-----
