Simplicity for me and ease of use for users.  My general plan has been separate packages for stuff (GDAL & co.) needed by multiple other end-user packages (GRASS, Mapserver, QGIS).  And maybe for tools useful on their own (python modules, and yes, could be SAGA, OTB, TauDEM), if I have time.  And a little bit of whatever I feel like doing factors in there also ;)

I did consider an OSG/earth package, but never got around to it.  QGIS is the only thing I use that needs it, though I was briefly interested in OSSIM, and there were small build issues early on (now sorted out).

The main thing is a user bundling cmake script for SAGA, OTB and TauDEM.

Do you need any build info for those?  OTB isn't hard, just a simple patch.  SAGA is a bit of work because of missing autotools in the latest Xcode, and it needs wxWidgets.  TauDEM needs some work, a few of us are in communication with the developer to fix it up.

I think when I looked at it a year ago I was put off by Windows/Arc-centric nature of it.  ... ugh, just a quick browse of the source doesn't look good - mix of windows and unix line endings in some files needs to be fixed (maybe the compiler doesn't care, but it's hard to read), and assumption of available headers/libraries, like MPI.  This may not be an option for OS X, at least in the near future.  It's also disappointing that the author didn't use libtiff, so that taudem could support lzw compression and bigtiff.
