Having been involved in archival projects including archaic scripts, I can tell you that academics feel a similar that the Unicode consortium seems to be prioritizing rafts of new emojis over texts that would be useful to academics. Let alone trekkie fanservice. Just use the PUA, if you really feel that strongly about it.
AIUI emoji are a different working group to languages (also I _think_ languages of academic interest might be a different group to languages in current use).
