Honestly, after Zora became sapient, it seems like a cruelty to have her just sit around in deep space.
In Calypso, this was less of an issue, because of the implication that Discovery became sapient after centuries of floating about, developing sapience as part of that time, but Zora would be sapient from the get-go, and leaving a sapient being adrift and alone for Millennia seems like fairly unethical.
The converse is that making a specific distinction based on sexuality like that is also illogical in what is supposedly the enlightened 24th century Federation.
They’re not the ancients of the 21st century, who would be so concerned with such primitive things.
