Not sure why Jonathan got in a flap over it.
Mostly because it's not geodata, and it doesn't belong in the main
database, but also because accidents like this one do happen. A large
object like an outline can have adverse effects on a renderer or
editor, which is one of the reasons the coastline isn't rendered at
the same time as the rest of the data.
There are also other annoyances like if you download a small area that
the outline crosses in JOSM, do some editing then press "1" to zoom
back to all the data you downloaded, it now zooms to a massive area
instead of the small one you're interested in.
If this is the case, then it's a weakness of the editor & not a valid
reason to exclude meta-data. It should be able to clip around the
boundary you downloaded.
Also, no-one has ever explained what use these outlines are. If you
want to see if some set of imagery covers an area you're editing, you
can just look at the imagery. What does having the outline achieve?
I edit at zoom levels greater than z17, the most detail level at which
most (all?) background layers display. I'm surrounded by Yahoo, but not
directly over my area so I don't, by default, have it turned on because
it has adverse effects on the editor. I use these meta boundaries to
remind me I'm entering a usable image area as I enter a long way, such
as a river.
So given that it does some harm, and appears to have no benefit,
that's why I'm against outlines appearing in the main DB. By all means
save them as .osm files and save them on the wiki or in SVN, but not
in the DB.
Are you really expecting the typical mapper to be able to want/need to
understand SVN? If so, then I believe you are misguided.
Remember, you are posting on the Newbies forum.
