I know, and I question the need to have this lower limit on the helper
restarts.

Only if max_requests is set relatively low compared to how buggy the
helper is. It should only be set low if there is serious problems, in
which case you actually want to have it restarted even if the request
rate is high.

As long as the helpers behave reasonably the daily rotation done as part
of the log rotation process should be sufficient.

idle timeouts is best managed in the helpers imho. And if this was the
gole there would be a need for a "restart_interval" option rather than
min_alive, placing an upper limit on how long the helper is kept
running.
