I don't think any stylistic data should be added.
Metadata should not modify the document in any way, it should only
describe the document or add additional things to it.

Having stylistic info ~kinda (it's possible to argue it doesn't)
breaks this definition.
Enforcing putting the metadata at the end of the file (slightly) helps
to avoid this.
