Given the strength of := binding, I'd discourage against this. |

Causing portage resolver catastrophes to solve a "it would be nice if ..." problem |
| 12 |
is a bad trade-off. |

:= Should be restricted to things that it is *necessary* for. |
| 15 |
|
| 16 |
What I think is needed is a weaker version of := which is advisory: that is, portage |
| 17 |
ignores the binding in entirety unless portage options dictate "rebuild things even if |
| 18 |
strictly not necessary" |
| 19 |
|
| 20 |
And this levity should mean portage should be more amenable to break graphs |
| 21 |
to make install possible. ( Whereas with := , the presence of such a spec causes portage |
| 22 |
to have tantrums when the underlying dependency changes ) |
