Yes because in my definition for \startamode I start a buffer which reads everything
untill the delimiting \stopamode and stores it in memory, afterwards you can access
the stored content with \getbuffer[…]. When you use \definestartstop to create
the environment you have only two commands which perform a few things at the begin
and end of the environment but you can do much with the content itself, the only
way to gobble the content is to store it in a box but than the buffer method is easier.
