I guess that the main purpose is for "real-time" applications, e.g.,
UI can afford to wait .1 seconds after some user actions, but it will
be great trouble to explain to the user why suddently the system is
frozen for 5 seconds, and, sure, real real-time applications are more
demanding. Note that since gc calls does not affect any program
visible functionality (except timing) VM is allowed to interprete them
as a hint, which does not mean that it do ignore them.
