When you say "it already has this option", do you mean this is what 
fallback-style is set to by default in this extension? Because, in fact, by 
default it's set to LLVM. Personally, I think it should be set to "none" by 
default.

Having said that, to answer your question, personally I think "fallback-style" 
is really an option that only makes sense when "style=file" AND a file is not 
found. If a user has a .clang-format file, and it fails to parse correctly, 
they would likely find it surprising that it would then ignore that file and 
use the fallback style. I would much rather it just fail hard and not use the 
fallback style in this case.
