Who interested in CPD (cont. prof. development) for software engineers?
Most “proper” professions have requirements on “continuing professional development” - assuming that a corpus of knowledge has been learnt then there are new developments or changes (ie new information on efficacy of drugs for anaesthesiologists)
What would that look like for software?
These requirements usually tie back to legal CYA mechanisms, government agency meddling, or rent-seeking licensing bodies. They have nothing to do with disseminating knowledge.
