That's not Potlatch, that's a requirement of the OSM API (and has always

As I said in my previous e-mail, "some GPX-producing software
concatenates different tracks within the same trkseg or trk". Certainly
I've seen tracks downloaded from some of the simpler Garmin eTrexes
which are just one single <trk> no matter how many times the GPX was
turned off and on again.
OSM best practice is that you should set your GPS receiver to record a
trackpoint at regular time intervals. If you are following this advice,
and your receiver/software combination produces a single <trk>, then the
3-minute limit prevents confusing and unsightly lines being drawn
between separate tracks.
