So by using PersistentList it just means that you can use: self.alist.append(1) in your code. The attribute, self.alist, is still saved even without PersistentList but it just means you have to be careful when writing to it.
PersistentX classes also usually subclass Persistent which means they get their own pickle jar. This can slow ZODB growth if you have lots of "big" attributes but where only one of them regularly changes: make the changing one a PersistentWhatever instance.
