" I just thought it odd, that in a subset of the HiFi (Fidelity/Truth) hobby, that people are actually striving for a F.R. plot that looks as if somebody was undergoing electro-shock therapy, when they plotted it."
If what I am correct about what you are referring to this is the result of lots of research that has been going on for some years regarding the different transfer characteristics to the ear of sound from a distant loudspeaker compared to a headphone or IEM placed directly on the pinnae or in the ear canal. In brief a headphone frequency response that measures flat just sounds incorrect and not at all " flat" to the majority of people. So the ideal frequency response looks like a plan for a roller coaster. The research ( primarily by Harman) continues to refine the ideal curve as knowledge grows.

I've looked at some of the better IEMs, that musicians might buy and their F.R.s are a lot flatter and I've read various comments by people using these better IEMs: Empire Ears, CampFire Audio, Noble, 64 Audio, Jomo et. al and it really has nothing to do with how the sound is transferred through the ear canal.
Some people just like/want the V-shaped sound signature and some don't, so these IEMs/earbuds are all over the map. Why these IEM/earbud makers just don't make them flatter and let the listener use their DAP's EQ settings, is what I don't understand?
The V-shape sound seems to 'not be due' to a design obstacle, but a preferred EQ for bass heads and rockers, but not for people who are completely into the human voice.
I haven't read of too many people talking about using Patricia Barber, Adele, John Coltrane, or the London Symphony, to review their new $2000 CIEM, so perhaps it's merely 'genre driven?'
Since a lot of this stuff is coming from China/SE Asia, perhaps due to travel/work conditions, people need the bass/treble boost just to hear anything? I don't know, but some of the graphs I've seen are highly exaggerated and people still love/enjoy it, at least in moderation.
Music choices I think, also come into play and heavy bass oriented music seems to be very popular these days. Hence the bass, lack of mid-range freqs and slight treble boost before a steep roll off.

Yes, some people do prefer a V shaped response. I think that it is because " audio" lost the meaning of " high fidelity" years ago , at least as far as civilians are concerned.
Once records ceased to try to replicate the sound of live performers in a room then the concept of high fidelity lost its relevance. If the sound on the record is synthetic ( as it is in just about all pop music records which are what most people listen to) then it is impossible to judge through experience what is or isn't likely to be correct. Thereon personal taste rather than accuracy becomes the arbiter. I blame the Beatles :-)
