Refs: #6888 (about Prettier 2.0), #6929 (about changing arrowParens to always)

Quote Props option was added in #5934 and is available since Prettier 1.17. Given that @azz did not mind changing the default value from as-needed to consistent in V2, I decided to open this issue to bring the topic to a broader discussion.

I understand that changing defaults can cause large git diffs in some projects. However for the benefit of newly created projects, I suggest that the problem can be addressed by changing prettier.config.js in existing codebases. V2.0 is a great opportunity for breaking changes like this.

WDYT folks?
