+0. Not all files with multiple dots in them are actually using them
to mean multiple file extensions. Every day I'm working with files
that use dots to separate words in a title, or have section numbers
("4.2.5 Yada Yada Yada.md" does not have a base name of "4"), etc.
Since there's no perfect way to pin these down, this needs to be a
completely separate feature, and it'd only really be useful for some
situations. So go ahead, if there's interest, but the current one
shouldn't be deprecated or anything.
