First document at root should not have special meaning when routing

Prerequisites

• I have added steps to test this contribution in the description below

Description

The first root document has been given special meaning when routing content. I can't find any background for this, nor any reasoning why it should have.

Specifics

Given this document structure:

All the blog posts are routable both at their expected path /[blog post URL segment]/, but also at /posts/[blog post URL segment]/. The latter should not be the case - at least not by default (more on that below).

For comparison, the authors are not routable at /authors/[author URL segment]/ - only at /[author URL segment]/, as expected.

HideTopLevelNodeFromPath

The HideTopLevelNodeFromPath config setting (see docs) is by default true ... setting it to false should include the root document URL segment in the blog post and author paths - and this does work for both blog posts and authors:

Testing this PR

Verify that V15 routes documents like V13 - with and without HideTopLevelNodeFromPath enabled.

Note: root documents are always routable by their URL segment even with HideTopLevelNodeFromPath - this is consistent with the V13 behaviour.

I've tested this and seems good to me.

I setup as follows:

And got the following, expected results:

V13

With "HideTopLevelNodeFromPath": true:

/home/test-1 - does not route
/test-1 - routes
/home-2/test-2 - does not route
/test-2 - routes

With "HideTopLevelNodeFromPath": false:

/home/test-1 - routes
/test-1 - does not route
/home-2/test-2 - routes
/test-2 - does not route

V15 - Before PR

With "HideTopLevelNodeFromPath": true:

/home/test-1 - routes
/test-1 - routes
/home-2/test-2 - does not route
/test-2 - routes

With "HideTopLevelNodeFromPath": false:

/home/test-1 - routes
/test-1 - does not route
/home-2/test-2 - routes
/test-2 - does not route

V15 - After PR

With "HideTopLevelNodeFromPath": true:

/home/test-1 - does not route
/test-1 - routes
/home-2/test-2 - does not route
/test-2 - routes

With "HideTopLevelNodeFromPath": false:

/home/test-1 - routes
/test-1 - does not route
/home-2/test-2 - routes
/test-2 - does not route
