I'm in favor of Valentin and I know these are not our father's Phillies but I just suspect they want the veteran. And it makes sense too, especially in light of Kingery, because if he comes up fast then you'd just be sending Valentin back to AAA quickly.
And it wouldn't hurt Valentin to still get a half-season in AAA, he's only 23, he's coming off the injury and he still only has 65 career games there, with a sub-.600 OPS last year. I think the Phillies already know what they have with him, he's a viable future bench player, but he may not make the team better than a veteran would in the immediate future. So you let him play in Allentown and you bring him up after you trade Hernandez or give up on Franco, if that's how it plays out.
His advantage, of course, is being on the 40. To me the question was always Florimon, he's presumably not sustainably the hitter we saw last season, but it was a Blanco-esque performance, they raved about his leadership, and they surely must have told him he had a preferred - if not binding - track back to the MLB roster when he agreed to re-sign.
Long-term it might be easier to have your utility guy come from the minor league free agent pool than to devote a 40-man spot to him each off-season, unless he's demonstrably better. So I guess there is that to still learn about Valentin.
