Is horizontal drywall backing needed where wall meets the ceiling?

Working on a renovation. I’ll be hanging new drywall on my wall, but the ceiling still has its old drywall which isn’t being replaced. The wall does have a top plate, but it’s above the ceiling, so there’s nothing to fasten the top edge of the drywall to where it meets the ceiling.
Should I add horizontal blocking between the studs at the top for backing, or does it matter?

You do not need blocking.
Only if you're going to put up crown moulding
On large crown I made up backer blocks first I could spot glue and tack to the stud and/or joist layout. Slightly smaller than the full blocking space behind the crown.
On cabinets, that are out beyond stud layout, a necessity.

…..if you get my drift.
Original question? I suppose for a fire blocking concern you’d do it. Electricians coming later for a remodel wouldn’t.
Instead of blocking for fire with wood I’d use mineral wool and to get a better insulated wall.
Thanks everyone! I hadn't even thought of crown moulding in this context, looks like I've got some backing to put up.

A single flat block between the studs won’t give you much help with usual crown molding. Standing it upright between the studs would help a bit for fastening the bottom of the crown. But that’s not going to help on the top.
You’d still be better off adding the angled blocks mentioned above.
I am curious about the credentials of those answering this question and leading who knows how many people down a dangerous path.
You need blocking at the midpoint of the door, extending out three bays, a couple studs in the corner to tie the walls together and give you the ability to get some sheer strength from 5/8 drywall, or sheer panel the entire wall with plywood, better option. When your amateur ass starts a fire in that switch box, the block at the top of the wall stops air feeding that fire which in turn provides easy access for the fire to get right up into your attic and it will give you a little sheer strength in that chopped up wall. .

kinda rude there, sparky. your suggestions are reasonable, why the attitude?
