Can we avoid the new folder in root?
And maybe reuse the l10n folder instead?

And maybe reuse the l10n folder instead?

The idea is to drop the l10n because in all other cases (all apps out there and also all folders in the server) this holds the actual l10n stuff - except in the root of the server, which is quite cumbersome.

Also the logic of the extraction code now uses this folder as indication of the root and therefore is a lot easier to understand, because this is the only way it works and it works for all apps and the server. I will do additional tests later on this.
