The warning about not setting a parser or plugins has false positives when using the syntax option

When setting the syntax through the syntax option instead of setting the parser option, the warning about doing nothing is displayed by postcss. But I have a custom parser thanks to the syntax I set.

@stof wait a second. Why do you need to use PostCSS without plugins and with the same syntax for parser and stringifier?

postcss([]).process(source, { syntax: scss })

In this case, input will be equal to output.

@ai I have a case where I generate some scss based on some other scss. As part of this, I inline all imported files into my main AST (before running other plugins removing lots of things from the AST). So here, I parse the input to get the AST and insert it to replace the @import node in the other tree. I don’t stringify it directly.
