That is awfully close to just discriminating against candidates who have families or especially single parents. This level of gatekeeping that a programmer who decides to have a full life outside of work is inherently an inferior programmer is a really superficial way to look at it. Equation passion with "Is this person willing and able to spend 60 hours a week coding" is a disgusting attitude that should just completely end in this industry.

In my entire career the single most talented Programmer I ever knew was a single mother who logged off the computer every day after 8 hours period, and choose to spent her life with her kids.
