I wonder to what extent. Self-love/self-acceptance alleviates it completely.
Accepting and loving the fact that I'm female through-and-through made a huge difference in my happiness, absolutely! It's just that it's made me even
happier that everyone else recognizes that I'm female, too.

So no, self-acceptance did not completely alleviate
my dysphoria. That was only the beginning. And even that depended on finally realizing who I actually am, something each of us can only determine for ourselves.
It really depends on what actually triggers dysphoria in the first place. Not everyone reports the same experience. Some transitioners get dysphoric only with respect to certain aspects of their bodies, others get dysphoria with respect to their social identity, and many face it on all fronts. I don't think we get to choose. Just like we don't really get to choose our inner truth; rather, it is something for each of us to discover.
The thing is, emotional responses happen subconsciously. And we don't have direct access to our subconscious processes. We can't just change our emotions by will alone; we can only address how to deal with emotions as they surface, and even then there's a lot of stuff the body will do automatically, before one is even consciously aware of the emotion.
How to proceed, then, depends on self-conception and lived experience, including feedback from our subconscious processes. And that's always going to differ from person to person. Each of us can only really know what "works" through trial and error, not to mention a lot of self-reflection. I know women who rue their public transitions, and those who rued non-disclosure; I know people happy on both paths; I know people who changed their minds about this, in both directions. I suspect one's emotional response to various kinds of gendering depends on one's self-conception as well as one's sensitivity to other people, none of which we actually control.
What we can control, to some extent, is whether we put ourselves in whatever position it takes to maximize our happiness.
Mind you, early on in transition the ritual of coming out was crucial to my happiness. This had the effect of changing how people related to me, specifically with regard to the gendering (including a whole slew of social expectations) I'd receive. It was
effective, because at the time my embodiment wasn't particularly good at eliciting female gendering, hence why I'd been misgendered all my life. Eventually, though, I got to the point where my embodiment was so good at eliciting female gendering that I soon learned that the "acceptance" of "indulged" gendering that I'd previously requested wasn't the same.
The truth is that I'm not an island. I respond, automatically and subconsciously, to other people. I'm happiest when my inner truth is reflected by everyone else. I'm lucky that I could actually come to know this, first hand.
