How do you envision Reisen's "development" to generally have affected her?

So about a month ago I asked a Reisen question about how she used to be considered newbie bait, but I now come again with what I think is a much more interesting question, proposition whatever. Aka, what kind of a person is Reisen now versus back then? Has she gotten development?

What I mean by this is how the fandom Reisen and canon Reisen are very much different in that canon Reisen beneath the timid, "friendly enough" surface is actually a pretty arrogant and inhumane person, at least according to SWR and Sixth Sense I believe. Even in SSiB she made fun of the rocket the SDM crew had conceived of until Eirin just said that it is an almost perfect rocket which shut Reisen up.

Obviously these were all in the earlier days of Windows era Touhou, and ever since 9, where Eiki calls into question Reisen's selfish act of desertion, up until her ULiL and LoLK story, it does feel like she's mellowed out into a pretty decent and level-headed person (by Gensokyo standards). But still, what I find quite interesting is how she hasn't completely shed her past behavior. In FS she's pretty adamant in telling Marisa off quite smugly by not understanding Lunarian tech, or in FDS with the whole "short ears" thing.

There's also another can of worms with AoCF and that other FDS thing where Reisen's got a lot of pent-up frustration and, let's just say complicated feelings beneath her surface even after all this time. Obviously, ZUN himself has stated that the reason he even gave Reisen a blazer was to highlight her ever-changing personality, or inconsistent personality.

But to return to the topic at hand, how do you envision her character "arc" or general character to be like? A once stuck up person who has mellowed out into a decent contributor to the society of Gensokyo, a wolf in sheeps clothing kinda deal, or a blend of both in that she has gotten nicer but has not completely shed herself out of her previous smugness and arrogance?
