This is probably mostly good news -- and it's true that Canfranc is sorely in need of an albergue ; but the section that they're talking about investing in is principally used by weekend and holiday walkers, whereas the section immediately north of Jaca remains quite seriously deprived.
Furthermore this quote "El objetivo general de este proyecto es desarrollar una oferta turística común" quite clearly suggests that tourism, not pilgrimage, is the focus (though we'll still benefit by default), though of course running the pilgrim infrastructures as businesses for purposes of profit has been a common theme on the Aragonès for I believe quite some time (pacem the few genuinely amazing albergues on that Way).
But if they can provide a bit less tarmac on the Spanish side and a bit more trail, that'll be good.
And it would be fantastic if they could do the same on the French side, in that final section which is a Spanish GR on French soil, as some quite lengthy stretches of that route can sometimes be pretty dangerous to walk beside in that heavy traffic.
