Conflict with Spark 3.1.2 scala version

When trying to use Beam with spark 3.1.2 we are running into this issue :

InvalidClassException: scala.collection.mutable.WrappedArray 

As explained here : https://www.mail-archive.com/issues@spark.apache.org/msg297820.html

It's an incompatibility issue :  spark 3.1.2 is compiled with scala 2.12.10 but this issue is fixed only for scala >= 2.12.14.

It seems that this issue can be fixed :

=> either by compiling spark & beam with a scala version >= 2.12.14

=> either by upgrading the spark version used by beam to 3.2.0, which can be compiled with scala 2.13

Do you know if the switch to spark 3.2.0 is planned ?
