   > @pjfanning There is an issue with keeping backwards compatibility while 
implementing projection support for MySQL - 
[R2dbcProjectionSettings](https://github.com/apache/pekko-persistence-r2dbc/blob/main/projection/src/main/scala/org/apache/pekko/projection/r2dbc/R2dbcProjectionSettings.scala).
 This class needs a new attribute for `dialect`, and since it is a `case class` 
there is no way to not break it. Is it okay to break backwards compatibility 
and convert this to a class, or do you see a different way to proceed?
   
   Could you add a 2nd constructor to the case class that has the legacy param 
list and that calls the changed main constructor, setting a sensible default on 
the new params?
