Its a shame there arent more questions for developers or agency people. The frustrations I have with WP these days is that if I create a custom solution for a client site in Dec 2021 it will probably be broken by deprecated WP methods or declarations by Dec 2022. Of course it might NOT be broken, but it might be – so my solution is rendered unstable and I have to explain to a client “this might break and I can’t predict why” and then convince them to assign budget for addressing these random changes in implementation.
