Should this be an error instead?

Should this be an error instead?

Good question. It might be wise to error, given that there is a path to remove the error and publishing by accident could be nasty. @tanushree-sharma thoughts?

[petebacondarwin]

Talked to @tanushree-sharma offline and we agreed to go with an error. Thanks @threepointone for the suggestion.
