Well., obviously because GNU Emacs tries to find a 'startup file' which
might be either just elisp., or compiled elisp., or gzipped elisp.,
etc., which can be in different locations and not just in the root of
your home folder. Different people want to arrange their configuration
files in different ways.
DTrace is surely a good tool for profiling and instrumentation., but
that does not mean an application should cut down its features just
because it is resource expensive to have them.
