A bit more context on this: the signalk Derived Data plugin can provide a value based on values from different sources. When one source dries up but the other does not, the resulting derived value is still updated as if were based on valid data. Which it is not anymore. It's a signalk thing but no one seems to worry about it. An example would be True Wind Angle, which is based on Apparent Wind and Boat Speed. When the wind feed freezes, you still get True Wind updates as the boat speed updates come in - no indication of anything wrong. This might be the concern where the guy on the forum referred to.
I don't expect this issue to affect the workings of pypilot, as pypilot does not seem to require signalk-generated derived data and I expect pypilot to recognize when any source goes stale EDIT: based on the signalk timestamps. For myself, I'll burn that bridge when I get there and worry when the sails go flapping ;-)
