Yes, it's worth it. Multiple-model (in this case multiple editor) learning has huge benefits. I would specifically define different generic levels of mastery (for example by using examples of your common editing cases) and then start to chip away at the lower levels in each editor. Track your progress. Your studies will be more resilient to adaptation this way. You may also be able to create bridging-shortcuts that you define in JetBrains and also set up in other editors, or vice versa. Or snippets, maybe you use Espanso in all three for example. It's always worth diving into this. You already have the forward-looking planning and contingency mindset which you demonstrate for us in your post. Add the execution-experimentation-analysis mindset now. You'll get immediate benefits. The contingency side will still be there when you need it later. Otherwise by giving too much contingency attention too early you can get stuck in a foresee-withhold loop without making any progress or learning anything new. Good luck and share your results when you can.
