There are actually others: lb, lw, dx. See https://www.unicode.org/reports/tr35/#UnicodeLineBreakStyleIdentifier

lb and lw are only for line break, which Intl.Segmenter doesn't support.
dx is not widely used or implemented, and I've raised questions about its utility.

Needs feedback from @Constellation. Also, @FrankYFTang pointed out that changes are needed in Appendix A/B. |

Sorry, I think we need additional changes that I forget to mention in TG2. A. We should also change B. The internal slot of Locale should also include "ss" C. We should also add a getter in section 14.3 which return either "none" (default) or "standard") |

For Intl.Locale constructor, the default value for "sentenceBreakSuppressions" should be undefined. (Comparing to other options, such as "calendar", "collation", "hourCycle", "caseFirst", "numeric", "numberingSystem")
