This may be related to the use of arcs and not to the use of symmetrical constraints arc

It is just a warning. There is indeed a redundant constraint in your OP, which is the point coincidence. The symmetric to X axis will constraint the arc center on to X axis. So, instead of a point coincidence, you can replace it with a point on Y axis constraint.

The enhanced warning message is most likely due to upstream changes in Sketcher solver

There is still funny behaviour going on with this. I am not sure if this is really working as intendend.
