Yes, I did know about more common abbreviations before implementing the current naming system, and I explained exactly why if you would go back and read.
And if I am ABSOLUTELY not going to change the naming system, my answer is:
If the current system solved the issues I listed previously in my answer, especially when I want to add extremely large numbers, then why bother to change?.
I can give some abbreviations for large numbers.
dr: C
ds: UnC
dt: DoC
du: TrC
dv: QaC
dw: QiC
dx: SxC
dy: SpC
dz: OcC
ea: NoC
eb: De(cicentillion)
ec: UnDe
ed: DoDe
ee: TrDe
ef: QaDe
eg: QiDe
eh: SxDe
ei: SpDe
ej: OcDe
ek: NoDe
el: Vc
em-u: Un-NoVc
ev: TgC
ew-fe: UnTgC-NoTgC
ff: QagC
fp: QigC
fz: SxgC
gj: SpgC
gt: OcgC
hd: NogC
hn: DuC
10^903 would be TreC, 10^1203 would be QanG, 10^1503 would be QinG, 10^1803 would be SesC, 10^2103 would be SptG, 10^2403 would be OctG, 10^2703 would be NonG and 10^3003 would be Mlnln (one of Jonathan Bowers' -illions [the actual name is millillion or millinillion). 10^2595 would be QaSxgOctG. I definitely understand that you will keep the current abbreviations, especially more so if you're concerned about or dislike long ones. Your third point in the message where you explained why you're using the current abbreviations makes sense, as "zzz" requires typing three letters instead of a high number. However, there's the hypothetical scenario where someone who plays Console Idle and at the same time is curious about the actual orders of magnitude that in the game are represented by "ar", "aff", "ck", "bl", etc. Even if it's unlikely to happen, that's not 100% guaranteed, especially when you're not in the lives of every single Console Idle player.
I can always add an option to switch between naming systems for the curious players.
However, given the long names such as QaSxgOctG, this thing will be ugly when being displayed, such as when hovering over a hardware, or in store, and because of how big it is, it will cause breaking points on some small screens, making it even worse.
Finally, imagine such names being displayed in achievements, players will not catch which number is bigger.
