Should zinit support ~plugin or ~[plugin], like zsh-snap?

[psprint]

Zsh-snap supports useful ~[plugin-name] expansion and completion. I think that it's a useful feature. Could zinit support it too? #381 and #464 are my PRs that get close to it, however I think that the square braces add much to the comfort of entering the plugin ID. Should we look at zsh-snap source and add the same feature to zinit? Or change it a little, like e.g.: to use ~{plgname} or some other variant? (hash -d doesn't allow special characters in the hashed entry name).
