There's not enough time left to meaningfully fill another 500,000 pixels; there's still a ton of white space on the current canvas. If the place time was shortened, it would have to be down to something like 5 seconds to be impactful. Changing the "rules" to that extent this late in the game feels silly. There's plenty of empty space as it stands.

Just my 2 cents, though.

Why did we resize at all? This completely prevented all competitions about space that makes the canvas so much fun. A lack of resources sparks creativity!

that's when people lack place that creativity and diplomacy begin between communities. Better have a beautiful small canvas than an empty big one

+1

If you do choose to expand though, maybe make it so you have a pool of maybe 8-12 pixels that can only be used for fresh canvas and then 4-6 for overwriting?
As shortening for non-touched pixels seems there could be an exploit to get more normal pixels?

Absolutely dont resize.
