To add to what Yasu already said, re-advertising with zero prefix behavior
could further not work in all cases ( so not a generic solution )
for example when you your router has some prefix with AL bit set ( /128)
then those prefixes are Not added to intra-area prefix referencing network
LSA and you have to keep it in intra-area prefix referncing a Router LSA,
therefore you have to maxage only some prefixes but not all of them ..
