It’s easy to do for everyone who learned the Patronus spell and the Hogwarts teachers do use that way of communicating frequently.
I think it should be common knowledge in the wizard world that you can send those messages.
The Defense professor highlited that sending messages via Patronus is an important part of fighting wars.
Given that people in the armies cared about how to fight in groups I think it’s likely that it’s something that you discuss at dinner table conversations.
I was under the impression that it was a secret method of Dumbledore and his allies. But I can’t substantiate that from memory. Besides, for someone already capable of casting a Patronus, it really is easy to guess once you know it exists—Harry did so on the first try.
Harry could have taught the method easily to any Patronus casters in the Great Hall and then they could have used it. But he didn’t have the time. And once Harry left, of course NPCs wouldn’t see themselves in the role of discovering new magic in order to take responsibility for something that wasn’t their fault.
Harry closed the book and put it into his pouch. “Chaos and Sunshine both have soldiers that can cast corporeal Patronus Charms. Corporeal Patronuses can be used to convey messages. If you can’t learn the spell, Dragon Army will be at a severe military disadvantage—”
That happens in chapter 47. I doubt such an event would happen without Draco asking other people whether the Patronuses can be used to send messages and making sure that people in his army know about it.
I don’t think Draco would be willing to reveal that he can cast the Patronus. Not after he publicly didn’t even try to learn it, and presumably told everyone else what he told Harry, that it was a “Gryffindor spell”. Harry had to cash in a favor just to convince Draco to learn the Patronus at all, and we haven’t heard of him using it afterwards.
Even if he wouldn’t be willing to cast it himself, he has non-Slytheren students in his army who probably can cast the spell.
Telling them to use the spell in that fashion is useful for him.
Draco is good at using other people for things he doesn’t want to do himself.
We can just enumerate the students who can cast it, they were listed in the appropriate chapters. I don’t know if any of them would have stayed at Hogwarts over the holidays.
I accept it’s possible that these students have already learned how to send messages via Patronus, since Harry said he was going to teach his soldiers to do it.

Are you sure? We have account from what happened in the class for first year students and about the dementor. We don’t have any accounts what happens in the classes of more advanced students. We don’t have any accounts of their battles either.

You’re right. I keep forgetting that students are still segregated by year.
