That means that unless you look through the history there will be no
evidence that it was once derived from another source...but, once you
have surveyed it, I don't think it is derived from the other source
any more, so this is fair enough?
It may be, if (say) the name came from NPE and you forgot to write the
name down while you were there collecting the GPS trace; in that case
"source=gps;source:name=NPE" might be appropriate.
There are quite a few "countryside" roads near me that look NPE traced
(i.e. the offset from other GPS traces is consistent with the NPE
Potlatch overlay offset) but have no source assigned; I've added a
source of something "looks like NPE" or similar when updating other
attributes but not the position (i.e. I see that somethings a dirt track
from one end but don't go down it to collect a trace).
