First of I want to say thanks for this work!
I'm still relatively a beginner developer. From reading this standard it appears to me that a "resources" directory is analogous to a "vendor" directory in a composer project. (I could be completely wrong)
Considering the relative popularity of composer in PHP projects, how does this standard reconcile the two? Should the "vendor" directory substitute the "resources" directory in a composer project?
Can the two folders be seen as conceptually being the same?
