I was wondering the same thing, as far as I can tell though it doesn't look like its used for the updating of views, this is defined here: spark/src/Console/Updating/UpdateViews.php
and makes no mention of those files.
I could be missing something but I think that's all the code for the updating.
Also seems odd that he would have just missed this when cleaning out the code, can't see why else it would be there though?
Gotta say as good as the laravel documentation is… the Spark documentation really lacks…
I've a confusing problem, where ONLY the auth views use the stock spark "layouts/app.blade.php" template…
it's the same @extends("layouts/app") line in every single template of my spark app, but only the login/registration,… etc templates use something out of the spark vendor directory it seems
