My question is: I'm a bit worried if this boot sequence is still safe to run. What happens e.g. if there were Flash errors? Does it still makes sense to skip the verification, or wouldn't it be better to accept a longer boot since the risk of errors is too high?
We cannot answer this question for your.
You already realized that you are trading speed for security when you switch off the checksum verification.
It depends on your use case and your project's requirements if this acceptable or not. If you're building a consumer grade MP3 player or a TV remote control, then it's probably fine. If you build a distress call system or a remote control for medical equipment the technical requirements may be very similar, but your evaluation of the speed vs. risk question may come to totally different results.
Best regards,
