As of now we could have both. FF sensor in small body already exist. It is Canon EOS RP.
Here is small Sony with FF and fixed lens for years as well.
I don't need to read three articles about something very obvious to me.
I like FF sensors and I like small pixel counts on them. Canon 5D, Leica M-E.
Obviously if you want to work in macro, pixels will help. Or blow it on the canvas.
But if all you want is many pictures of your family, nobody needs more than 10MP pixels for it. Absolute majority takes pictures with flea sized sensors on mobile phones. And next to none of them cares for pixels and sensor size.
BTW, I not considering DPr as something worth to read after they refused to deal with hateful and racist comments on lomography products.
