See https://www.semver-ts.org/formal-spec/5-compiler-considerations.html#strictness for the arguments for turning on noUncheckedIndexedAccess for libraries. In short, it helps prevent shipping accidental breaking type changes to library consumers. (Note the link also suggests turning on `exactOptionalPropertyTypes`, but I still have doubts about it, as it would not be helpful without a specific coding style, which is hard to enforce.)

The link also suggests turning on
exactOptionalPropertyTypes, but I still have doubts about it, as it would not be helpful without a specific coding style, which is hard to enforce. By moving both options to the baselinetsconfig.json, we can ensure strictness across the ecosystem.
