Sure, but usually these things can be accelerated if you are blocked and can't do other work. It's usually expected that you are doing other work while waiting, be it ops, reviews, invention/simplification, design, coding for other projects, or networking with coworkers etc. It's not uncommon for a firm to be amendable to spending some portion of time on outside activities such as education, event planning, or (sometimes) a side business/startup.
If everyone is spending 5 minutes working every 4 weeks... why would you hire extra people outside of contingency coverage?
If everyone is spending 5 minutes working every 4 weeks... and your company isn't paying for "hurry up and wait"/hot-standby personnel, how the fuck did your company mismanage things so badly so that they're paying their people full-time programmer rates for 60 seconds of labor per week?
If my workload is such that I can work four "full time" jobs and every one of my employers is happy with my work product, then that's nothing but great for everyone.
