It seems rather unconventional and currently I can't see enough
advantages to convince me personally.

In shell commands you will typically need to escape the character, which
would affect commands like `nix-env -i foo\@ver` but that shouldn't
happen too often. What would be worse, if this delimiter was used in
filesystem paths like /nix/store/hash-fooname at version/... we would have
to escape all of the occurrences and I'd expect many scripts to break.
