Maybe we could split them from RDEPEND to some kind of EXTRA_DEPEND (or |
| 12 |
something else) to fit this purpose. |

The problem of relying on that is, for example, following situation: |
| 23 |
1. I install all my system without thinking on USB modems as I don't |
| 24 |
have one. |
| 25 |
2. Months after that, I need its support, but I need to figure out I |
| 26 |
need to manually emerge sys-apps/usb_modeswitch to get it used by |
| 27 |
modemmanager, as I don't rebuild net-misc/modemmanager every day, I get |
| 28 |
no notification at all to know I need to emerge that package. |

Even for me I tend to periodically check world files of machines I |
| 41 |
maintain, and it's tedious, we shouldn't promote people to easily |
| 42 |
contaminate their world files. Currently, most people will end up having |
| 43 |
a lot of unneeded packages installed in their systems after years of |
| 44 |
usage due this way of happily telling people to install some random |
| 45 |
packages to get extra support. |
