Is it the bare minimum though? Not everything needs to be nor should be a gleaming E-ticket expansion. DHS needs attractions that will draw guests within the park without drawing guests to the park.
So far, this looks like a quality project that will do exactly that. In my opinion, refreshing tired spaces is the opposite of doing the bare minimum, which would be letting it be and doing nothing.
Furthermore, the experience fits perfectly in the theme of Disney’s Hollywood Studios, unlike The Animation Experience at DAK, which is an upgrade in and of itself.
