It's simpler to implement, and it allows much more fine-grained control:
you don't need a keyframe in order to switch layers, and you don't need to
consult NTP timestamps (which might not be available) to ensure that time
doesn't flow backwards when you switch.

In the specific case of Galene, SVC is rock solid, while there are
occasional visual glitches when switching simulcast streams.  And the
simulcast switching code can be used to frighten little children, while
the SVC code way simpler and more elegant.
