Please refer to the previous thread for the rationale:

No *functionality* is removed.  If you look at patch 5 in the series,
I've only reduced the number of visuals with accumulation buffer that
are exposed.  The accum visuals that are exposed a full featured (i.e.,
double buffered, depth, and stencil), so any applications that may
require an accumulation buffer will not lose any capabilities.
