QGIS currently does not support No/Unkwon CRS. This leads to lots of confusion for new users. In addition, CRS is not always applicable to layers loaded in QGIS. Here are a couple of use-cases:

Attribute tables with no geometry
When you load a CSV as an attribute table with no geometry, QGIS automatically applies the default CRS. This can trigger the OTF and results in some confusions.

Unknow CRS
Sometimes user simply wants to add a layer and doesn't want to have a CRS assigned to it. Examples of that can be found in MapInfo or CAD.
