Subject Re: Does Zipkin need to sign a SGA ?

+1 with a minor addendum.

Smallish contributions do not constitute own Intellectual Property Rights if they do not pass
the bar for the 'threshold of originality'.
Of course this bar is a grey area. But it's afaict established sense that small bugfixes,
and minor contributions (no whole feature) does not pass this bar.

So in practice you only need the written ACK from people who contributed a more impacting
feature or enhancement.

Example: Fixing a spelling error or clarifying an existing sententence does now constitute
originary IP. Adding a whole page of documentation surely does.
And inbetween is a grey area.
