Data.Vector.Generic.New.unstream (and others) can't be specialized

I don't pretend to understand this, but GHC 9.8.2 reports for vector-0.13.1.0 with -Wmissed-specialisations

src/HordeAd/Core/AstSimplify.hs: warning: [-Wmissed-specialisations]
    Could not specialise imported function ‘Data.Vector.Storable.Mutable.$fMVectorMVectora’
      when specialising ‘Data.Vector.Generic.New.unstream’
    Probable fix: add INLINABLE pragma on ‘Data.Vector.Storable.Mutable.$fMVectorMVectora’

I think I had no warnings like that half a year ago.

Hah, actually, -fspecialise-aggressively fixes this (I had to set -fno-specialise-aggressively on github CI because it OOMs otherwise). Sorry about that noise. Closing.
