you shouldn't need me to tell you that "Ragatha is a repressed lesbian" and "Dumbledore is gay" are not the same, but aside from the obvious reasons they shouldn't be compared, it should also be said that Ragatha's case is a lot more meaningful than just simple representation for its own sake.
the key word is "repressed". this is important partly because it justifies why it didn't come up in canon—she hasn't worked through those feelings yet, much like Jax hadn't worked through her feelings until the finale. but it's also important because being a repressed lesbian, specifically, informs a ton about Ragatha's character, if taken as canon.
she clearly feels some form of connection and kinship to most of the women in the circus: with Pomni most of all, but also with Ribbit and to a lesser extent with Gangle. she is unable or unwilling to understand these feelings as potentially romantic, of course, so she tries to express them in other ways—in particular, as something more than a simple reciprocal friendship.
she tries to be a mentor and protector to all of these women in some way, because she's able to recognize that she wants something more than just a mutual platonic relationship. (most likely, she drifts toward this particular unique dynamic because it mirrors how she protected her siblings growing up.) in some ways, this is a good thing—everyone needs some help dealing with the trauma of the circus in general, and with Jax's behavior in particular, which only makes the role feel more fitting! but its source is less about actually protecting others and more about reassuring herself...which makes a lot more sense when she's also, subconsciously, trying to convince herself those feelings aren't romantic in any way. as a result, she ends up pushing people away by being overly friendly and defensive, because she's not fully taking their feelings into account.
what I find fascinating is that, in a sense, this also serves as a foil to Jax's repression. she buries her trans identity, and allows her feelings of self-hatred about it to manifest as rudeness, cruelty, and hostility, which ultimately drives people away. Ragatha, on the other hand, buries her lesbian identity (even deeper, to the point of likely having never properly recognized it), and allows her feelings of affection toward women to manifest instead as overprotectiveness and overfamiliarity, which also end up driving people away. she reflects the same moral: that failing to contend with your own queerness can break down your relationships with those around you and harm everyone, regardless of how you try to repress it.
this similarity is, imo, the other reason Ragatha isn't explicitly stated to be lesbian in the show itself. Gooseworx implied in another ask that she chose not to include Pomni and Ragatha's conversation at the end of "They All Get Guns", because it'd repeat the story beat of Ragatha's conversation with Kinger earlier. this is a similar example, with the same character at the center of it: having Ragatha unpack her identity issues with Pomni's help (especially in the finale) would be a very similar beat to the end of Jax's story, just less impactful because nobody dies about it. a scene like this wouldn't add much to the story as a whole, and while it would add to Ragatha's character, her arc also works without being explicitly tied to her identity. any scene that would've covered this was likely either never considered or cut early on, for exactly that reason.
