Overriding the starting Home Directory: is it rude?

Description of problem:

A customer of ours uses a Custom Notebook Image. 

In previous versions of RHODS (1.15), when the user would log into the terminal, their location would be their home directory as defined in the image, i.e. /home/jovyan. 

Now, in recent versions of RHODS, when the user logs into the image's Terminal, they land in /opt/app-root/src/. 

Upon investigation, in the YAML for the notebook pod, the following statement appears

This workingDir statement apparently overrides the defaults of the customer image.

Workaround:

We have told the customer to: 
In your dockerfile, you have a statement that says:
CMD ["start-notebook.sh"]
replace it with
CMD ["/bin/bash", "-c", "cd /home/jovyan ; start-notebook.sh"]
then, rebuild the image.
And that seems to have worked.
