They are indeed just as bad.  (Uhm, Queens is worse- the imported boundary
excludes some inhabited areas of the borough.)

The same import also has some weird boundaries labeled "territorial waters"
that don't close, don't align to baseline, coastline, 3-geographic-mile
limit, or 12-nautical-mile limit. I'm going to delete them as well, at
least in the areas where they're glued to political boundaries.

The neighborhood boundaries in Queens are well defined - all the locals
know where Corona ends and Flushing begins - so I wouldn't object if
someone wants to maintain them. They were political boundaries until 1898,
and things like 'postal cities' mostly still follow them. But I'm not
likely to do it.

I might redo the community board boundaries from NYC GIS, but it's not a
high priority for me. I got started on this because the Adirondacks and the
Niagara Frontier had no political boundaries at all in OSM. When I got to
where there were political boundaries, I saw they were all misaligned,
sometimes by a km or more.  It's turned into a project of redrawing all
1600 municipalities (which, of course, incidentally redraws alletim
because I find imported misinformation everywhere I look.

Thanks for the confirmation that the imported junk is indeed junk.   I'll
tidy it up in the places where I'm working.

As I move down into Queens and LI, I can supplement the work with strong
local knowledge - I was born in Far Rockaway.
