Presumably not, modulo memory charms.

Well, he mentions it casually to McGonagall, who did not see it before:

If I'd remembered the Patronus earlier!

All that tells her is that he figured out the Patronus somehow. She doesn't know that there's a 2.0 version.

Neither do F&G, really; it's unique and humanoid, but the real secret is that it kills (un-kills?) Dementors.

The real secret is that once you know why it works, you can never cast Patronus 1.0 again. The humanoid form is a clue, so Harry needs to conceal it.

Killing Dementors is awesome, but in the short term the benefit of showing that ability off does not outweigh the risk of leaving all wizards everywhere defenseless against them.

It's also significantly brighter than normal ones (Patroni? Patronuses?)

It was known by the teachers that he could cast Patronus, but that what it was was secret, I think.

Hmm, I thought that only Quirrell, Dumbledore, Draco and Hermione knew about it, and only the first two saw the form.

He basically mentions in front of the entire Wizengamont that he can perform a patronus charm.

Lucius Malfoy's eyes narrowed. "By the report I received, you cannot cast the Patronus Charm, and Dumbledore knows this. The power of a single Dementor nearly killed you. You would not dare venture near Azkaban in your own person -"

"That was in January," said Harry. "This is April."
