I'm really excited by this! I haven't been keeping up with the 2022 stuff, and I'm quite pleasantly surprised.
I will admit to not liking using '@' for notation much at all in any language - never mind Ada - but I'm really looking forward to having a solution for the problem it solves. I do love me some long names, probably even by Ada standards, so it really will be quite nice. I also can't really think of a good viable alternative beyond simply replacing it with a symbol I just happen to find more visually appealing. So... oh well. It'll probably fade into the background soon enough.
