Re-reading the bug report, we had come up with a blueprint of a possible
solution  but failed short of implementing it [0]

[0]  https://issues.guix.gnu.org/20255#35

Even the --search-paths command become 0.2 s, I don't think it'll
satisfy all parties, so the solution above still has merit, I think.
Perhaps we should try to implement it, unless you see a problem with it.

Thanks,
