That is in fact why it's deprecated, yes. It's been deprecated long
enough that we should probably remove it entirely in the next release;
old users should have had time to change over by now and new users
would be better served by a compile-time failure instead of a run-time
warning.
Further, AFAICT, it is always 3D
It's always LIBMESH_DIM dimensional; a constant defaulting to 3 and
set at configure time. Usually 2D problems are cheap enough that
people don't bother to worry about optimizing them, but there's
occasionally someone who has to run a zillion 2D problems as the inner
part of an optimization or uncertainty quantification loop and so we
try to keep --enable-2D-only from regressing.
forcing an anyone wanting to use it would have to know otherwise how
many matter or just loop over wasted zeroes.
Right.
