Since we already have the mi we can use it directly instead of deconstructing it.

@wsmoses How come Enzyme.jl reverse CI takes over 1 hour nowadays? If expected, can you bump the timeout?

[wsmoses]

for better or worse sadly it takes ~1 hour [52 mins or so] atm. From our tests it looks to be spending most of the time on inference, which we're hoping to bring back down.
