Hmmh, i wouldn´t like all items need only a short rest... you should at least have a nice glas of whine with a pulverized pearl in it, stirred with an owl feather... of course, its very easy to find out that it is more balanced as it appears to be, but it should be a bit harder to conceive, that you can enwrap it in flames.
I like, that there are still cursed items and more powerful items which need a (maybe one specific) ritual to identify: a cursed item would tell you its a different one, an artifact only reveals its magical plus.
Now the default assumption should be, that players who can´t identify will actually use the item until they find out how it works, and so it is much easier to give them an unnoticed artifact or a hidden cursed item...
Sometimes players will notice, that they should be a bit more careful to handle unidentified magical items, because if its cursed you may not want to touch it. So a ritual to identify it without handling it could become interesting.
