Update:

I have change my opinion on this, and I don't think I require this any more. If this is ever implemented I would probably use it, but I really don't mind this behavior at all. If you want to read more, I wrote a post in dev.to

# Options (if any):

Input:

<input type="button">

Output:

<input type="button" />

Expected behavior:
I would like an option to prefer void element tags over the current implementation of self-closing element tags. I understand why is this the default behavior, as this is xml compatible, but several style guides suggest the usage of void tags as they are valid HTML5 tags. As I understand in the option philosophy, if there is enough usage from developers there is a justification to add the option.

# Options:
