No management required can be better than "easily managed".

This is a more recent implication of direction:

However you're showing a bias which steers away from a better
solution, not needing the overhead of fully-featured NTPd isn't a
defect it's an advantage.  A Laureline is a better NTP response
provider than an RPi (see mike cook's plots)  and doesn't require
*any* configuration or monitoring (but mike cook shows graphs for
those that care about such things).  No compiling, no OS updates, no
conf file fiddling, no management.  Literally plug and play.  There is
still a to-be-fixed leap-second issue but it is documented to support
keyed connections and multi-cast.
