what is the compelling reason for this?

The reason for adding the docs or adding templates://?

1. It is used in multiple plugins but the parameters are not explained anywhere.

2. I want to create a plugin that adds structured data (json-ld) to the page. It processes the page.header and if it finds an entry it searches a corresponding template.

For example:

structured_data:
    local_business:
        name: 'Pizza Restaurant'
        address: [...]

// Check if a template exists for the given data
$template = 'structured-data/json-ld/' . $key . '/' . $key . '.json.twig';
if ($locator->findResource('templates://' . $template, true, false) === false) {
    continue;
}
$this->grav['twig']->processTemplate($template);
[...]

It won't work. The reason is that twig isn't using a stream and paths can be added later, too.

I dont understand, it works for me. And the event to add path is run first, so all templates should be in place. But I am no expert here, however I've need a solution to lookup the templates from a plugin.
