[HOT] Question about background image alignment

I'm also looking at a ~7.5m misalignment in parts of Monrovia, when 
viewed on Bing imagery in JOSM.

Should I assume then that JOSM alignment is "always correct" or at least 
always *canonical*?  [e.g. if there really is an offset it can be 
corrected *en-masse* when either better imagery or real measurements 
become available]

If so, there's a significant error source somewhere in the HOT datapath. 
  I haven't done any editing via the website since I work in JOSM, so I 
don't know what editor it brings up and what imagery, but it seems like 
any offset in that path is systemic and should be corrected ASAP before 
all these areas get mapped with mixed offsets.  I've realigned a number 
of roads in that area and drawn stuff in outlying areas that may get 
"messed up" by future edits if not done in JOSM....
