Don't break compound words at their hyphen if the prefix is less than the specified minimum

[MikeTO]

Some words like x-ray should never be hyphenated but Publisher will break at their hyphen because they contain a regular hyphen, regardless of the hyphenation settings.

Addressing this just would need just a tiny tweak to the breaking algorithm, not a change to the hyphenation dictionaries. Instead of always breaking at a regular hyphen, Publisher should not break if the minimum prefix is greater than the characters before the hyphen. e.g., if the minimum prefix is set to 2, Publisher wouldn't break 6-pack but would break six-pack.

I don't think this needs to be an option with its own checkbox. If you set the prefix to 3 you really don't want 2-character prefixes followed by a hyphen, but Publisher will break re-elect at the hyphen even with a prefix of 2.

I believe ID handles this even worse than Affinity, it never breaks at a regular hyphen. Or at least it used to, I don't know if they've improved the algorithm recently, but this was a frequent source of complaints. ID would break mother-in-law after 'moth' even if there was space to break at the second hyphen.

I should add that even though ID has a worse hyphenation algorithm (because it won't break mother-in-law at a regular hyphen), its refusal to break at a regular hyphen means words like x-ray will never be broken at the hyphen in ID.
