I'm iffy on the vertical aligning as I generally don't like that since they're annoying to modify. However we rarely change this stuff

I feel like Bedrock being the foundation and staple that it is, the code base should be "beautified" and as readable as possible from the end-user– especially as most of it is "dev-facing" (e.g. application.php).

I do understand the annoyance to modify the vertically aligned docblocks though– but it is indeed a fact that it is rarely to be changed.
