They are.

Years ago i wrote an error-reporting library for Unix systems that gave
precise diagnostics in a lot of situations -- e.g. the existing error:
$ mkdir /bin/sh/boy
mkdir: cannot create directory ‘/bin/sh/boy’: Not a directory

and mine,
$ mkdir /bin/sh/boy
mkdir: cannot create directory ‘/bin/sh/boy’:
mkdir: /bin/sh is a regular file and connot contain subdirectories.

People hated it at the time saying it was too verbose. But it was aimed
at trying to identify the likely actual problem rather than reporting
the symptom, exactly as you say.
