I'm not even sure it was ever about excrement actually.
This is for example the root of the word Kakistocracy: https://en.m.wikipedia.org/wiki/Kakistocracy
Sort of like a long time ago tattoos were super rebellious, but times have changed and now not having a tattoo is being hyper rebellious, misspelling your kids name or playing phonetics games used to be rebellious but now times have changed and it would be hyper rebellious to name your kid "John". I didn't misspell my daughter's name at all, and now she doesn't fit in.
Cultural drift in names is not new at all. Decades ago I dated a girl with a legal name right out of Tolkien's Silmarillion. A former boss dated a daughter of a hippie with the first name "Marijuana", which is so rare it might be doxxable. At least some gen-x kids received rare names.
Also in my genealogical research a lot of German, or generally axis powers, names disappeared around WW1 and WW2 for obvious reasons. They had immigrated a century ago and their grand kids dropped a lot of European vowels and consonants, making my genealogical research extra complicated. You might be amazed at the prefixes some -smiths or -schneiders used to have. My handful of Irish ancestors randomly added and subtracted letter O and some vowels, also.
I am completely baffled as to what you want from me here.
Explaining how to pronounce a name with multiple vowels in a row is goddamn hard in a lot of places.
