Either you gamble and don't replace it, or prevent engine disruption by being proactive and replacing it before it fails.

Only true for interference engines. For non-interference engines this is not a catastrohic issue, more of an inconvenience. Memories of a 1980 Volvo wagon which ate its timing belt at 30k miles and fortunately suffered no ill effects.
And the timing belt maintenance is in the owners manual when you buy a car. I haven't found the section in my manual where it specifies the interval for replacing the IMS.
Has Porsche ever come out and defined this service interval, or do they just let owners discover it on their own? I don't use the dealership for more than parts -- has anyone ever had a dealer recommend an IMS replacement proactively?
