Holy Necro!

To answer that question:
the STO Novel "The Needs of the Many" makes it clear that the Gorn have a caste system and that it's the same as in the Pocket Books novel series.
And why Gorn females would not have mammery glands should be so blatantly obvious noone should have to say it, but I guess I'll need to: they are reptiles, not mammals.

I disagree because then it would make me feel compelled to make females too and I already have too many characters already.

Humans are the only playable mammals in the game, yet breasts seem to be pretty universal among females of different STO species.

Bajorans are not mammals?
Vulcans are not mammals?
Klingons are not mammals?
Betazoids are not mammals?
Do you actually know Star Trek?

I'd support this only if we can have a one-time gender change on any existing Gorn/Lethean/Nausicaan captains or boffs already in play. Even if there's no difference at all other than a word in the bio saying "male" or "female," I'd really want this. My Gorn captain is based on a female character, not a male one...

Caitians are mammales also

Putting mammery glands upon gorn women would not make the mammels, it kind of gives a distinction or seperation between the genders. Also, holograms have a chest and they dont need them, and what about the saurian women, I'm prettyu sure they are a reptial race and yet they have bo.obs. I say it put distinction between the races. I have a gorn toon and if they did make gorn women playable I would like that distinction. If you ask me, when MMO's make characters that there is little to no distinction between the genders of race it make it boring and slightly annoying. For example, the Warforged race that are on the dungeons and dragons online game.

And besides, have you ever seen fan fiction or fan art of lizard or repitialian women, they do put bo.obs on them.

That said female members of the species would likely have notable differences of physical appearance.

Last time I checked mammary glands are one of the defining aspects of mammals so putting those on another genus and saying it doesn't turn them into mammals is like saying when you remove the hair from the top of someone's head you don't make him bald.

That holograms have them is for the simple reason that they are supposed to be a simulation that contains familiar characteristics.
And in that case we know the Doctor on Voyager got only those characteristics that were visible (he was a "Ken-Doll") while anything else was a later addition.

With regards to the Saurians there's the same question as there is with the Cardassians: how non-humanoid are they given they're appearently evolved from something other than mammals yet have mammalian features like giving birth to live children?

In case of the Gorn it's clear that's not the case.
And to be blunt: are so unimaingative that you can't think of any other way to differentiate male from female that grafting humanoid characterics on them?
There are other ways of achieving that.

For example in many species females are a lot bigger than males.
So why not use that as a starting point?

Or like in other cases, the males have a larger head while the females have a larger body (relatively speaking)

Or like in case of the Grass Snake the heads have drastically different shapes:
