Klingon, Tengwar, and Cirth were rejected mainly because nobody wants to deal with potential intellectual property issues. Sitelen Pona was rejected because the proposal was barely even a proposal, plus it doesn’t appear to be a very stable script <https://www.unicode.org/L2/L2025/25010-script-wg-report.pdf#section6.6>. I actually can’t find any proposals for Sarati at all.
I suppose the issue with scripts for conlangs (and just conlangs in general) is that almost all of them are used by only a tiny number of people, and only a tiny subset of *those* uses them for any “serious” purpose. With stuff like Volapük you can at least make the case that there exist documents with historic significance, but there’s simply not a lot of incentive to put all that effort into supporting a writing system that’s essentially just a diversion. Toki Pona is nobody’s first language, and from what I can tell the Latin alphabet is by far the most popular choice for writing it anyway. Someone would need to demonstrate that the lack of Sitelen Pona in Unicode actually causes material problems. Am Di., 26.
