Colour me crazy, but I've always thought the temptation to explicitly add more and more letters to these kinds of acronyms was a little counterproductive (referring to 2SLGBTQIA+). Like... I remember when it was LGBTQ+. The plus was meant to represent all sexualities. Listing 5 items felt like more than enough to clearly convey the nature of the list.
But then when you go and explicitly pull some group out of the plus to better represent them, I always wondered what that implicitly said about those not explicitly pulled out. Like suddenly groups in the plus feel less important, because we've taken out the special highlighter for some. So I'm not surprised that more sexualities got loud and demanded to be added as well, further watering down the nature of that "plus". I feel a little bad for those in the plus when it's considered in poor taste to say anything shorter than 2SLGBTQIA+.
But I guess that's just how naming by committee works, it's hard to convince a group of people who want to be explicitly included about the implicit downsides for others. I suspect the initialism will only get longer rather than ever becoming any shorter.
