A new issue has been raised regarding the Default CRS requirement
It currently reads *"There should be a default Coordinate Reference System
(CRS) that can be assumed to be used for coordinates that otherwise have no
specification of the CRS."*

Issue 28 <https://www.w3.org/2015/spatial/track/issues/28> was raised to
question this requirement.

Let's dedicate this thread to discussing this issue. Are there people that
question if this should be a requirement? Or is it about the phrasing of
the requirement? If so, it would be good to have suggestions for
alternative wording.

It could be that what is needed is some more context to the requirement. Is
this meant for existing coordinate data? Or data that have yet to be
published (using the yet to be formulated best practice for geometry
encoding)? Or both? In my mind, adding context like this could lead to
unwanted restrictions of the freedom to find a good best practice.
