install with '--upgrade-dependencies' requires '--force-reinstall'

I'm using a development cut of cabal install from a few weeks ago, so this may not be relevant anymore (I'll upgrade soon to try the changes to --enable-tests and install soon), but I found this behavior odd: When using 'cabal(-dev) install --only-dependecies --solver=modular --upgrade-dependencies' to test my package with new dependencies, I am then told I need to use the flag '--force-reinstalls'. Shouldn't this be implied by '--upgrade-dependencies'? Thanks, Antoine
