Hi,

What happen if the submodule (spiffs) mantainer will not include the feature (or doesn't reply to PR) I propose in its repository?

In practice, the PR I propose here it is subjected to the PR on submodule.
Should I copy the spiffs module in components folder of my project and go ahead with it?

Thanks
