The syntax plugins for Prisma ORM auto-format their schema files in a similar way [1]. It bothers me so much that I can't bring myself to use their solution - which I realise is incredibly petty :)
I couldn't really put into words why this column style formatting bothers me so much for this type of data, but thanks to one of the comments there I think I do now: this information belongs together horizontally, but it is formatted in a vertical manner which takes more mental processing.
