I don't think we made a formal decision, but I think we should. I much prefer
the -no-indent syntax--I'm not a fan of significant white space.
We also have this page that talks about code style:
https://cwiki.apache.org/confluence/display/DAFFODIL/Code+Style+Guidelines
That might be an appropriate place for that.

Did we formally agree that we will reject any Scala 3 code that depends on
indents in the primary Daffodil code base?
I know we have "-no-indent" in our build.sbt which enforces this, but I
don't see the keyword "no-indent" in the dev list email history.
I also thought we had a coding-style guide on our Wiki, but could find only
this
https://cwiki.apache.org/confluence/display/DAFFODIL/Coding+for+Performance
We should consider writing a scala coding style guide that subsumes that
page, and that justifies our scalafmt and other guidance that we otherwise
have to enforce in ad-hoc review comments.
FYI: Some of the arguments in favor of no-indent are well made in a recent
blog
https://alexn.org/blog/2025/10/26/scala-3-no-indent/
Though there are numerous more arguments why in large code bases, as
opposed to smaller scripts/tools, this indent-oriented syntax is
problematic.
