As swift has already dropped support for the ++/-- operators and C-style for loops it makes logical sense that dropping the ternary operator (or replacing with a more Swift-like idiom) should follow.

Training users to expect source-breaking churn would be highly damaging to the language. The removal of C-style for loops and increment/decrement operators came with sufficient justification beyond their being inherited from C. I don’t think there’s a sufficient justification for this change, especially with the bar set high for such changes.
