Flag: --incompatible_auto_exec_groups
Available since: Bazel 7
Flipped in: not yet
Planner removal: not yet

Current status
Implemented and almost ready to flip in Bazel@Head.

Short summary
Automatic execution groups select an execution platform for each toolchain type. In other words, one target can have multiple execution platforms without defining execution groups. Migration requires setting a toolchain parameter inside ctx.actions.{run, run_shell} for actions which use tool or executable from a toolchain.
