(I had opened this as a GitHub Issue but it looks like feature suggestions for the main repo are redirected to here)
I noticed that a plugin that I want to contribute to, does not have a LICENSE file - so I opened an issue requesting that the status of the code be clarified.
It might be a good idea to add the creation of the LICENSE file to the template so that the author is prompted to add something. An alternative option would be to add a hint to the README file to suggest that the author clarifies license and contribution guidelines when they release or announce a new plugin.
