I’m sure Reddit will tell you “no” definitively. But I think it’s important to understand that language has changed a lot. “Man” in old English had a very different connotation than today. Man really meant; mankind in old texts. Not strictly male. 

Now that being said, the move to “person” and “folk” makes sense to me semantically. We adjust!

"Language is arbitrary and conventional".

Words have meaning based on what is accepted by society.
