Shortcodes with optional {content}

If I am not wrong, when I use {content} in a snippet, I cannot use only the opening shortcode, i.e., I am forced to use [shortcode]Some content[/shortcode]. If I use only [shortcode] (without the closing [/shortcode]), the output will include a literal {content}, with braces.

I have some snippets with optional {content}, so it would be nice if I could use only the opening shortcode when there is no content to be added.

This is a suggestion for the future. It is not a priority, though, since I can keep using the snippet normally if I simply put a white space between the opening and the closing shortcodes when there is no content to be added.
