I'd like to ask what's the motivation behind this.

I thought that contractions like "it's" vs "it is" are so common that they are not considered vulgar or low-quality English. Maybe I'm missing something.

I'm a native English speaker (so my opinion only represents a minority of users), but I like contractions. I don't see the need for consistency. Sometimes I'd like to be casual, while other times I would really like to make a point, with a slightly different voice (<---- purposeful example in the previous statement of speaking inconsistently on purpose).

Cheers!

I like Ryan's point, as the last sentence did indeed feel the way it was meant to - even for a non-native like me (although, you could say I've become quite native concerning reading text written Ryan 😉).

One of the things I like about writing docs for Symfony is the touch of casualness surrounded by the Symfony brand. While I've learned to not use contractions when writing academic papers, I think we should not strive to become too close to an academic paper.

Well explained 👍🏻

Let's close then

It's clear !
