That’s an area in need of improvements, thanks for looking into it!

FWIW I’m not entirely convinced by the approach.  As discussed earlier,
I’d like to experiment with a notion of “build rounds”: the first round
would build a profile without any hooks, the second round would,
depending on what the profile contains, rebuild it with certain hooks.

I don’t have anything to show yet, though…
