In the 33 years I have owned my Model A I have read numerous articles regarding safety issues with original fans cracking at the rivets and possibly flying apart. My Model A did in fact have a cracked fan. The Model A world has numerous replacement options.
There does not appear to be the same problem with the Model T and 3 vendor sites I have looked at only carry steel pressed riveted fans. Is the difference the fan rpms?

Could be the RPM thing, but T fans are also known to toss a blade. May not be as common as the Model A. Could have something to do with the way the Model A fan is constructed and material it is made out of along with being 2 blade.

The original two blade model A fan is hollow, and internal corrosion can be undetectable, and look perfectly fine, until they aren’t. All the originals are well beyond their life expectancy, and should be replaced. That is, if you value your sheet metal, radiator and/ or skull. The new ones are very nicely made, solid aluminum, powder coated. Wish they wouldn’t powder coat the pulley groove, though.
It’s easy to inspect any normal T fan by looking or feeling for visible cracks. Not so with model A.
