I can certainly see the benefit here, but wouldn't that still result |
| 36 |
in (arguably) unnecessary (re)builds? If implemented well it'd also |
| 37 |
result in depcleaning them when they're later unneeded, too, so I |
| 38 |
guess it's a wash in that sense. |
| 39 |
|

Again, I'm not against it. In fact I'd probably use it, because some |
| 41 |
packages are really picky. I just don't know how well it would fit |
| 42 |
into the existing design at the code level. |
