Some observations:

1. Our (seamark:) tags are not rendered or interpreted by any the land 
map browsers, applications, etc., so do not present conflicts to the 
wider community. Only those specialist browsers & applications actually 
interested in seamarks will be affected, so we need to have any 
discussions with those people, rather than the community as a whole.

2. Many land map imports, landsat tracings, and even member surveyed 
edits have similarly large positional errors, so why are we being 
castigated for importing inaccurate data? The whole idea of bulk imports 
to get a starting point from which our mapping contributors can survey & 
refine.

3. We do not use the FIXME tag, we use the seamark:fixme tag.

4. The intended users of the NGA LoL are commercial shipping who 
probably don't care about a 200m positional error. They just need to 
know an approximate position, then look out of the window and/or use 
their radar to actually locate the mark.
