I was surprised to find no examples of others having taken similar approaches

Such processes are I/O-bound, there is therefore little or no benefit to be gained from using more cpu resouces to perform the process.

If you take a look at the cpu usage of your single-threaded, process whilst it performs the task, it will probably average somewhere between 5% & 10% of a single cpu. The speed of processing is entirely limited by the speed of the disk. Throwing multiple threads at it will most likely slow it down.

In the absence of evidence, opinion is indistinguishable from prejudice.
