Well there is a blog I found in the Japanese fandom recently that fairly explained it.

Every fan began to have this version of Miku that they themselves interpretative her as. Its the start of the Derivative OC era which lasted for several years right until 2013 when a lot of it died off. Each producer wanted to stand out so would vary the voice and call it "Princess Miku" ("The World is Mine" Miku is known as that particular derivative). With hundreds of producers doing it, some variants like Haku and Neru stood out and got really popular while others like Zatsune Miku just got abandoned by their creators. Giving them voices made them stand out more and even made them marketable I suppose.

A lot of the reason its not as popular as it once was is that... well... There is more Vocaloids now. In those days, it was more about making the most of the few vocals that were released to produce dozens of characters.

As I said a lot of it has died down with the event of more Vocaloid being released. The result of the derivative also varied between vocals. You tended not to find many on Gumi from that era as she didn't have a lot of "give". Miku was better at giving more tone variants then Luka but Luka's were better and Miki out bested Miku in that area as the first Vocaloid to be able to fill 16 tracks with good quality unique vocal variants. Miku append did provide Miku with a lot more choices, but we're talking about single vocals here not multiple.

I think there seemed to be more encouragement as when XSY groups were added in late V4, Ah Software encouraged people to own particular XSY pairings by using them to create new OCs.

The west is basically poor in understanding what makes these derivative stand out and why they all of them exist. Some of these variants had very much become associated with their owners and there have been arguments over them. Mostly because a particular "setting" can be associated with a Vocaloid producer's work specifically and they feel their identity gets infringed upon if others use it. Usually its their fans that cause this hassle and not so much the producer who came up with the idea.
