As such, I'd rather have ‘now’. In practice, this is still not a blocker, because extra inputs for search paths affect neither the purity nor the union-build much. > Also, this sounds like adding a new feature (multiple profiles for > Guix Home) at cost of an extra (known) bug (these multiple profiles > don't share search paths). Hyrum's Law might also come in play here. Thus an alternative would not be sharing search paths, but making those search paths themselves a part of manifests. However, while either would be doable if we bikeshed enough, having a known bug persist while we solve an important other issue is imho preferable to waiting until we all agree about what's to be done with it.
