Long time breeder says humidity control isn't actually needed?

[Stewart_Reptiles]

I have not check humidity in individual enclosure in.............well actually I never have

I measure the room humidity, I pay attention to the look of my enclosures and my snake sheds

Temperature is the only thing I check everyday with a temp gun getting random reading in different cages and that's when I use a hot spot which I do not most of the year.
