I've actually seen this coding style for the same reason:
val x = Seq( // format: off
1
,2
,3
) // format: on
Tolerating or as we have now, requiring dangling commas everywhere feels
like a bad trade off when a simple trick like this also works.

I don't know if it's a very very good reason, but I think the main
benefit is making diffs more clear when adding to a list.
Without trailing commas you get a diff like this:
Seq(
1,
- 2
+ 2,
+ 3
)
But with trailing commas the diff is this:
Seq(
1,
2,
+ 3,
)

Why oh why did we ever do this?
Is anyone very attached to this dangling comma stuff in our current
scalafmt rules?
I am at this point, vehemently opposed to this code style, and very much
want us to switch back to not allowing dangling commas.
I've spent hundreds of hours now working this code
