-Wunused false positive on compiletime usage

[som-snytt]

Compiler version

3.5.1

Minimized code

package p:
  val code = "\"hello, world\""

package q:
  import p.*
  import scala.compiletime.testing.*
  def test() = typeCheckErrors("println(code)")

@main def test() = println:
  q.test()

Output

➜  snips scala run --server=false -Wunused:all testing.scala
-- [E198] Unused Symbol Warning: /home/amarki/snips/testing.scala:6:11 -------------------------------------------------
6 |  import p.*

Expectation

It would be nice if the lint were aware of compiletime ops.
