'cameras_*' isn't a valid use flag name, so the package mangler can't |
| 8 |
just pass the * through to the ebuild, which means it has to expand the |
| 9 |
value itself. But there's no complete list of every CAMERA value |
| 10 |
anywhere, so it can't. |

There were plans to fix this in EAPI 4 by requiring that IUSE be |
| 13 |
accurate. That would have allowed the package mangler to use IUSE to |
| 14 |
get a complete list of known CAMERAS and be able to expand * that way. |
| 15 |
Unfortunately, that feature got dropped, and so in EAPI 4 you're still |
| 16 |
allowed to make use of USE_EXPAND variables without making sure IUSE is |
| 17 |
complete. |
