Critical a11y fix requiring a breaking API change

Source: interviewintermediate

WHAT IT TESTS: balancing urgent accessibility risk against breaking-change discipline. OUTLINE: ship a safe interim fix, plan the breaking API as a major with deprecation and codemod, communicate urgency.

WHAT IT TESTS: whether you can weigh user harm against migration cost. ANSWER OUTLINE: assess severity and reproduce; if possible ship a non-breaking interim mitigation immediately, then design the proper fix; release the API change as a major version with the new behavior default-correct, keep a deprecated escape hatch during an overlap, provide a codemod and migration guide, and communicate the accessibility urgency so teams prioritize.
