Meh. Personally I still prefer them being Deltans
Why? Although there was no mention of the baldness factor in TMP itself, Gene Roddenberry certainly intended hairlessness to be a trait of Deltans. We see bald Deltans wearing Deltan robes (made for TMP, and headpieces made for Persis to wear around the Paramount lot) in TMP, ST IV and ST VI.
When Vonda McIntyre described one of Jedda and Zinaida's other partners (in ST IV novelization) as having "fine, rose-coloured hair down to his knees" I was very disappointed. It seemed to go against other excellent work with Deltans (such as "Dwellers in the Crucible"), although she was probably miffed that Jedda ended up with a thick head of black hair in ST II.
The Saratoga alien in ST IV is a marvellous makeup. So distinctive. The skin complexion they used on Nick Ramos was a pale orange, they created white contact lenses, and they gave him such distinctive long hair - the longest hair we've seen on a male Starfleet alien since the native Americans with braids in TMP.
I can't imagine the makeup artists saying, "Good morning Nick, today we make you into a alien from the same planet as Lieutenant Ilia." And he certainly didn't emulate aspects of Persis Khambatta's distinctive delivery - her accent was exquisite.
Similarly, the ST VI makeup artists would have explained to Kurtwood Smith that his makeup once appeared in ST IV, not TMP.
What's so bad about Efrosians coming from Efros Delta, the consensus chosen by recent ST novelists? Someone from Efros Delta might be called a Deltan for short. But they are not the same race as Ilia's people.
the name Efrosian never existed in any other official capacity besides the handful of stills, and the backstage crew who invented the term
Which led to its use in the licensed, approved "ST IV Sourcebook Update" by FASA. The same canonical weight as the ST IV novelization.
And then by "Cinefantastique" magazine, in their coverage of ST IV.
It was
years later that ST VI's novelization suggested that the UFP President wasn't Efrosian.
