I'm with you on the delays, especially since it's one sided, company doesn't loose anything, main inconvenicence is to the user so the company has to be incentivised to be on time (it may be even beneficial for the airport, since passengers would buy more overpriced stuff from waiting area).

I was referring to the case when an engine went bad and company had to use intermediate airport and accomodate all users for the night. Also you wouldn't want to punish company hard for admiting technical issues, since that might cause them to underreport and create dangerous situations.
