Ok, I found it (I think) in scribus150.rc. I edited this file, adding a
shortcut for ZWNBS. It still didn't appear in the shortcut list, and
also doesn't work. On the other hand, inserting the unicode character
2060 does work, so it seems either internally Scribus may be using the
deprecated U+FEFF, or it's ignoring this.

Nuking the shortcut section seems to clean it up, though still when you
open Scribus, there is no choice for ZWNBS, even though, once again when
I close Scribus, there it is in the rc file.

Maybe this is pertinent. In specialchars.cpp there is this section:

bool SpecialChars::isIgnorableCodePoint(uint ch)
{
	// based on list of Default_Ignorable_Code_Point in Unicode 9
	if ( (ch == 0x00AD)					  || //SOFT HYPHEN
		 (ch == 0x034F)					  || //COMBINING GRAPHEME JOINER
		 (ch == 0x061C)					  || //ARABIC LETTER MARK
		 (ch == 0x115F) || (ch == 0x1160) || //HANGUL CHOSEONG FILLER..HANGUL
JUNGSEONG FILLER
		 (ch == 0x17B4) || (ch == 0x17B5) || //KHMER VOWEL INHERENT AQ..KHMER
VOWEL INHERENT AA
		 (ch >= 0x180B && ch <= 0x180D)	  || //MONGOLIAN FREE VARIATION
SELECTOR ONE..MONGOLIAN FREE VARIATION SELECTOR THREE
		 (ch == 0x180E)					  || // MONGOLIAN VOWEL SEPARATOR
		 (ch >= 0x200B && ch <= 0x200F)   || //ZERO WIDTH SPACE..RIGHT-TO-LEFT
MARK
		 (ch >= 0x202A && ch <= 0x202E)   || //LEFT-TO-RIGHT
EMBEDDING..RIGHT-TO-LEFT OVERRIDE
		 (ch >= 0x2060 && ch <= 0x2064)   || //WORD JOINER..INVISIBLE PLUS
		 (ch >= 0x2066 && ch <= 0x206F)   || //LEFT-TO-RIGHT ISOLATE..NOMINAL
DIGIT SHAPES
		 (ch == 0x3164)					  || //HANGUL FILLER
		 (ch >= 0xFE00 && ch <= 0xFE0F)   || //VARIATION SELECTOR-1..VARIATION
SELECTOR-16
		 (ch == 0xFEFF)					  || //ZERO WIDTH NO-BREAK SPACE
		 (ch == 0xFFA0)					  || //HALFWIDTH HANGUL FILLER
		 (ch >= 0x1BCA0 && ch <= 0x1BCA3) || //SHORTHAND FORMAT LETTER
OVERLAP..SHORTHAND FORMAT UP STEP
		 (ch >= 0x1D173 && ch <= 0x1D17A) || //MUSICAL SYMBOL BEGIN
BEAM..MUSICAL SYMBOL END PHRASE
		 (ch == 0xE0001)					 //LANGUAGE TAG
			)

Maybe there is still some connection between ZWNBS in the rc file and
the old 0xFEFF? Entering 0x2060 as a unicode character does work.
