Probably.  The reason is that Gst::init() not only initializes
GStreamer, it also initializes glibmm (which it relies on) and registers
methods that wrap C types to correct C++ types for all the GStreamer
GObject and GstMiniObject derived types and all the GStreamer plug-in
types that gstreamermm makes available to be used in a C++ way.  In the
process, it must load all the plug-ins that gstreamermm makes available
(this is probably the most time consuming part though only for the
execution for which the plug-ins have not been loaded; the rest of the
executions wont experience so much a delay).  We know of no other way to
ensure that the C objects handled are correctly differentiated and
treated as appropriate C++ classes.
