A comprehensive answer is here:

https://www.aivosto.com/articles/control-characters.html

To preserve the integrity of conversions and interchange,
the control codes remain.

However, the semantics of the control codes are reserved
to applications.

So the control codes are in a kind of limbo.  They have
only an application-specific meaning but in the absence
of an application they are to be interpreted according
to  ISO/IEC 6429:1992. (Unicode 9.0 p. 822)
