If there is an adoption by majority of nowadays packages, why not go to the majority to simplify?
What is better for anyone who read and write code: to have a ‘standard’ expectation or have to adapt to many styles? I personally prefer PascalCase not because it is beautiful or what, but because it is more understandable when you have to use similar names in code for classes, methods or any other things that have to be distinguished.
‘Such As’ may be named SuchAS, if not may be confused to ‘Su Chas’ or ‘Suc Has’ or even ‘Suchas’.
naming can be anything but must be clarified, and PascalCase does it very well. I think camelCase does it also but not so well as PascalCase.
