Safety of using "s' and "e" values?

I am creating an interval and when the error is “missing or invalid start”, “missing or invalid end” or “end before start” the start and end value are null so I have been using Interval.s and Interval.e to create a new Interval that is valid.

The DefinitelyTyped version @types/luxon doesn’t have the “s” and “e” values so I wanted to check if they should be added to the type definition (happy to do that) or if there was a reason they weren’t and should not be?

I can’t officially support it, but if I were you I’d just use e and s until 2.0
