lumi schema & name property

[andrewfowlie]

I was looking at the schema, trying to understand which elements are required etc. I noticed that the lumi modifier schema gives the name as well as the type to be { "const": "lumi" }

https://github.com/scikit-hep/pyhf/blob/3d26434be836050e334190c212b1db1a6f7650c8/src/pyhf/schemas/1.0.0/defs.json#L115-L122

If I understand this correctly, it says that all lumi modifiers must be called lumi.

Compare this to other modifiers e.g., shapesys.

here, it seems like the name can be any string you want.

Do I understand this correctly? Is this lumi restriction deliberate so that there can only ever be a single lumi modifier named lumi? This kind of makes sense, although I could imagine wanting to have different lumi modifiers, especially if I was including both ATLAS and CMS data. Or is it a copy-paste error since it is the same as the line below it?
