It's more of a trade-off: I want the benefits to exceed the drawbacks.
Since I see this drawback, I'd like to understand the benefits so that
we can collectively make the good trade-off... Does this really need to
be in havana and why ? Or is it preferable to have it really early in
icehouse ?

Note that I can't really "veto" anything as long as the PTL wants it in :)

Damn, you escaped my trap :)
