Here's the nuance. If it flows naturally and isn't over the top, it's great. If it feels too planned and/or too much about the adult "spreading magic", it's weird and feel like some are trying to be CMs when they are not.
If you are with your children and naturally include others around you with glow sticks, etc, good. If you appear at the parade route with no kids and suddenly pull out Mary Poppins bag with toys that you planned weeks in advance and start playing with kids you don't know, it feels contrived and would make me uncomfortable. I'm not saying you have to have kids, but things start to stack and look obvious that you planned ahead to do this, which may concern parents (unfortunately, we have to be a bit suspicious of stranger motivations).
I was at DLR last week with my little one who fell asleep in stroller on way back to hotel. I took my glow bracelets off and handed them to the parents of two little girls on our way out and kept walking. I also gave away Space Mountain FP to a couple that had been standing next to during fireworks. All seemed natural and appreciated but I also didn't stay around to "watch them" enjoy the items and, in the case of glow bracelets was "parent to parent" with a sleeping child headed out of park. Had there been kids around us when we started using glow sticks, I would have definitely shared and it would have felt normal.
On an extremely hot day, I also noticed an obviously overheated older gentleman who took a seat on the bench next to me. As we were leaving, I handed him a chilled bottle of water from my stroller saying simply "here's an unopened bottle of water". He was pleasantly surprised snd thankful and I smiled and just said "enjoy" and kept walking. Again, I didn't stay to watch him drink it or get fawned over in appreciation. I just left him in peace, in a little bit better shape than I found him. It actually turned out to be a great lesson for my little one who commented on it hours later. I was able to make the point that small kindnesses go a long way toward making the world better and was glad he saw that I wanted nothing in return. I had something that could benefit someone else and shared it without a big deal.
I think that's the big difference to me -- kindness without a big deal. Unplanned, naturally occurring kindness with no expectation of participation in their enjoyment is spectacular. Packing extras in case, is great. The rest can be a little weird.
YMMV.
