As long as there is an option to turn off this feature and maintain good ol’ bruce syntax, I don’t see a problem here. Well, as long as there’s a no-brainer way/tool to convert from one syntax to another. Copy-pasting code is still very useful.
Speaking of indentation, scalafmt and codebase migrations, it’s just so happen that at my current place of employment, we wish to move to scalafamt. Alas, most of our code has a tab size of 4 spaces, and scalafmt doesn’t support anything other than 2 spaces. This is intentional “as it is recommended in official Scala guide”.
I would hate it if we end up with a significant-indentation oriented tooling and ecosystem without enough support to maintain the current syntax.
