Oh I see, that makes a lot of sense. Thanks for the info!
I guess the only thing we can still find out now, is if it's even possible at all, to actually randomly get HT/WT 0 from Home, and then ofc sending the Pokémon to SV and get size 0 the regular way (as intended by Home). I guess it's probably either 1/16512 odds, or locked to not be able to get size 0 at all. I'm assuming it's the same odds as SV though, so I guess it's just a matter of time until the first person shows up to state that they randomly got size 0 through Home.
It can be a new thing, just like shiny hunting legendaries, but instead finally seeing the Mini mark after 16 000 transfers
