Well, there are other people doing it, but there are some caveats.
The Alaska Satellite Facility got our polar projection working thanks
to Mike's help...he added the "magic" you see in the previously linked
example. Without that, the projection works, as long as you don't
actually specify Infinity for the wrap width (which goes against what
the documentation says) and as long as you don't try to do anything
with polylines. That is, points only. NASA uses a polar projection for
some of their data, and they are what I would consider "major players"
doing it, but I guess NASA either a) hasn't tried to do anything with
polylines/similar, or b) has started using Mike's trick to make it work.
For ASF, we needed polylines and polygons and such to work properly,
so Mike's addition helped fix that. If it helps your situation at all,
I'll point out that in the linked example, which still even contains
the "Copyright 2007 ASF" business, by the way ;) anything beyond the
equator from the pole you are looking at is clamped to the equator.
That is, if you had a line spiral around the earth from one pole to
the other, under a normal polar projection that line would spiral out
and then back in. In our polar projection, it instead spirals out and
then wraps around the equator.
Anyhow, not sure if any of that helps. Long story short, you
absolutely can do polar projections, it's just not supported, and
you'll have to ignore the documentation in one or two places. And, of
course, you'll have to provide your own map tiles, which you seem to
be working on. :)
