I'm considering avoiding too much plastering in one of our ceilings and gluing a reinforcement fabric in the ceiling. Apparently, you should glue it and then "torrolla" to attach it.
But is it enough to plaster in the "ridges" of the ceiling gypsum so it becomes flat but NOT in the short joints and NOT over the nail heads?

You have to plaster the ceiling just as usual. The reinforcing fabric doesn't hide any mistakes (well, maybe a little bit)
As I interpret your question, it's about whether you need to fill the short joints, the ones that do not have a filler groove.
The reinforcement fabric is not intended to replace joint filling. According to the gypsum manufacturers (and more professional paint stores), the joints should be reinforced with a paper tape that is embedded in joint compound. The paper tape is significantly more durable than all forms of fiber tape, etc. In theory, a joint that is filled with paper tape should become as stable as the rest of the gypsum board.
The reinforcement fabric that can be applied before painting has, as far as I understand, 3 different functions: it evens out the surface, as it is often visible when you paint on a filled surface, the joint compound compared to the paper surface on the gypsum board gives a different texture to the paint. It further strengthens so that the risk of cracks in the ceiling is reduced. If the ceiling still cracks due to movements in the building, the fabric can hide the crack. There are obviously limits to how much settling can be concealed.
