I want to clarify that these warnings are not going away with 2024.1. The warnings are intentional and are highlighting custom code patterns that we have identified as being problematic. The problems include security, performance and data integrity. The set of warnings will continue evolving as we identify more patterns to avoid.
The warnings will not stop your code from compiling or running. However, in the future, these warnings will become errors. So do heed them and consider alternatives.
