Exactly. Omni risks are high and rising plus damage the core tenant of Safe: Everyone. It was safe to sit still on Omni before, but the probabilities have now shifted and I have seen zero pushback that this is not the case (see summary list here).
This is true as well, and there is a high probability that when a team of programmers sit down to design a safe secure transition out, the flexible, programmable ERC20 with lots of similar contract example cases to draw from will be a lot cleaner secure choice than unprogrammable Omni and little similar transition cases. That is one main reason why Omni has no traction.
