Not really, but this depends on your workload.

Every reload gracefully shutdowns old workers. This means that if
there are long-lived requests (big downloads from clients with
slow links etc.) old workers may still be here for a while. And
they still consume memory and so on. In my practice shutdown time
reached several hours in some cases.

If you reload every 15 seconds and shutdown takes longer - you
have problem.
