Will SpamSieve ever be available for Spark?

24 year Mac user. Long time SpamSieve user. I now use Spark exclusively on all my devices—iMac High Sierra, iPad Pro iOS 11, and iPhone iOS 11.

Not looking for a temporary shortcut. Will SpamSieve ever make Spark a supported app as it has done for Apple Mail?

If I have to choose between SpamSieve and Spark, I have to choose Spark.

Thanks, Shocklaw
