I don't know about the size of the downloads, but is that *really* a problem? |

As to the system-* flags: I've been setting all of them except for system- |
| 23 |
sqlite since... they exist, I think. I make the exception to system-sqlite |
| 24 |
because it likely has a negative performance impact on other packages that |
| 25 |
depend on sqlite. However, it seems that at least system-cairo might be |
| 26 |
problematic in recent versions of Firefox, see |
| 27 |
https://bugs.gentoo.org/show_bug.cgi?id=558150. |

In general, I think it depends on how well upstream supports the flags and how |
| 30 |
quickly problems are noticed when using them, which might not be as quick as |
| 31 |
we like. |
