Personally I think it's great. There's dragons, birds, etc... so why not humans? I haven't made a human character per say, but I have 4 out of 5 characters based off human/humanoid characters. Only one of them actually has a preset that shows human clothes on, but I think it's perfectly fine to have such roleplays.
Besides, we splash a bit of human qualities in every roleplay (except the most realistic ones), for example: animals talking, thinking in languages/like us, wearing clothing articles like glasses, scarves or necklaces etc..., having humanized feelings like desire for revenge and names.
In short, I support and enjoy seeing human roleplays both in Bonfire and out.
