I am trying to find the nicest way possible to critique this post. While I am happy that you are posting in support of this feature being rewritten in the new version, reframing the request the way you did feels very ableist to me. As if it isn't a legitimate function if user need it to spell, but if they just use the functionality to save time by having short cuts for long phrases, it is somehow a better reason to have the functionality.
Your comment didn't change the way the functionality works, it only adds an additional way to use it. A perfectly good way to use it, but not a better or more important way. It is great to have multiple uses for the same functionality, but it is not great to imply judgement about the different reasons. I wish I had a less public way to mention this to you. I am sure that you just didn't realize the way that your message sounded.
