Smgono suspected keldeo quite some time ago Hawk, yes. PO never have. The chances are, due to releases and bans since then, the meta has shifted enough to be more in keldeo's favor, even with tornadus-t gone, rain seems just as prevalent as ever, and with sand being a bit more poplar, so is scarf keldeo as it works both on and against sand teams.
The only release/ban since then that I remember was Tornadus-T which was suspected at the same time, and maybe Deoxys-D (can't remember exact timing). The meta has barely changed since then (Deo-D HO lead being replaced with Custap Forry/Skarm) and Keldeo IMO is just as prominent as it was 3 months ago.
Keldeo is actually one of the few pokes that can actually Counter (albeit only once and without running something built to counter it, ie Ice Fang Gyara) Landorus-I after a Rock Polish if you send it in right after Landy comes in. Keldeo is bulky enough to take a Modest Sheer Force Life Orb Earth Power (IIRC) and hit back with HP Ice or STAB water move
This test is a bit pointless IMO, and it looks like Smogon just want to return the meta to BW1
