True, if we were talking about "Elf fans," which in this context we're not. If you were just a fan of Elves in the general sense you'd have quite a lot going for you between Elves of Blood, Void, Night, and Nightborne varieties. But we're talking about a more specific ask, and I think you know that (at this point you'd sort of have to). And like I said originally, it's an open question as to whether it's a deserved ask; but the request has been made all the same. It's been made for a long time, ever since the halcyon days of Classic WoW, when players first set eyes on High Elven exiles with their weird low-res models at the time.
"An" answer, yes, but in my estimation missing the mark pretty significantly from "the" answer. I would call them a different flavor of Blood Elf, myself, given that Umbric and his people were Blood Elves before they became Void Elves. I won't argue that the change was a prerequisite for them to shift factions from Horde to Alliance, either; but they still don't answer the original request because they're a different people on two levels of abstractions (one as former Blood Elves, another as altered by the Void into Void Elves). Now, whether or not one values faction identity or integrity over letting people play what they want to play truly is a subjective opinion.
The surfeit of options is not the problem, and never really was - the failure to facilitate the original request is the crux of the problem. The demand has categorically not been met, therefore it's understandable that those who value the prospect might be disappointed by the outcome. It would be akin to wanting a Playstation 5 for Xmas, but your parents instead get confused and buy you an XBox Series X instead. Both of them play modern gen games, sure; and they've got similar hardware, but it's not what you asked for or wanted. YMMV as to the severity of the proverbial recipient's reaction, but I think anyone can see where the problem is.
As for the more in-game rationale I still have not been sold on any reason why the existing High Elves exiles weren't chosen as opposed to the Void Elves. I've heard the many arguments, but all of them strike me as arising from a place of seeming Horde entitlement to both Blood and High Elves in the general sense. Stripped of long-winded explanation, the argument seems like "Blood Elves are High Elves, both Blood and High Elves are ours, and we will not part with them and the developers stand by it." Which, on the face of it, does seem to be how things are going - but it still feels like an entitled argument to me, and I can understand why those who want playable High Elven exiles on the Alliance side are by degrees upset by that outcome.
A transformed Void Elf from Silver Covenant High Elf is still not meeting the original request - it's closer, sure, and for some people it may be enough to satiate them, but it isn't the same thing and has the same lens of abstraction as the above, only one removed. I also doubt it will happen for several reasons, though I admit the possibility.
