I very much see this as a valid intermediate solution. Getting an estimate of 
the average spacing between trees along a tree row takes seconds. 

Exactly locating and mapping every single tree along a long tree row can take 
hours. And in the majority of cases, you are probably not going to be much more 
exact than a tree_row with spacing would have been, given the usual size of 
trees and the precision you can get from GPS or not ultra-high resolution 
imagery.

Which means that people would probably mostly draw a line, with the estimated 
number of nodes that there are trees, use the "distribute equally" function and 
tag them all as natural=tree. 

Congratulation, you've now used many nodes, and pretend an exactness of the 
data that doesn't exist, for zero additional benefit over a two node tree_row 
way with spacing.
