Do we need to set `-YdisableFlatCpCaching` for Scala 3? #1480

Open Friendseeker opened 4 days ago

PR #826 sets -YdisableFlatCpCaching when outputting Jar on classpath and compiler version is 2.12/2.13.

Do we need to do it for Scala 3? Or do we no longer need it since https://github.com/scala/scala/pull/6064 is merged?

Probably want to go back to the good old approach of... experimentally test original reproduction in https://github.com/sbt/zinc/issues/282 and see if the issue is reproducible without -YdisableFlatCpCaching.
