Is there a commonly accepted "best practice" for how to use the "Main Menu" vs the "Navigation Menu"? The descriptions in Core add to my confusion:
"The Main menu is used on many sites to show the major sections of the site, often in a top navigation bar."
"The Navigation menu contains links intended for site visitors. Links are added to the Navigation menu automatically by some modules."
I don't intend to start a debate. I'm curious if there's a best practice for how to use these, or is it entirely subjective?
