What use would a soap be that contained fat?

Very good for washing things with.
That's how (solid) soap is made (and has been since it was invented).

I thought originally it was oil saponified with alkali, with a more
liquid soap being produced with potassium, rather than sodium,
hydroxide. Maybe less than total saponification gives you an oilier soap?


nah. It was sheep fat or lanolin and lye, mainly, lye being caustic soda.
