Question on system design

I have a customer that insisted to have 24VDC outputs relay that controlled 24VDC relays that controlled 230VAC contactors to pilot motors.

He claimed that it reduced the size of the 24VDC power supply and limited the number of breakdowns. Personnally I was not convinced.

He clearly is not the man in charge of troubleshooting such a system.

And the man leading him is afraid to become irrelevant in the company so close to retirement.
I've seen this happen time and time again and to be honest, it scares the **** out of me as I don't want to become like that.
