Undisclosed Extra Y axis available?
One of my minor disappointments with the CORE One was that Prusa only specified an increase of 10 mm to the Y axis for a total of 220. But it appears there is a bit more on tap- you would just need a larger build sheet. I noticed the extra space left on the rods at the Y origin when printing.

And editing the start gcode to push the purge line back on a larger BL sheet shows there's almost 20 mm more Y available (less if you leave a bit of headroom and in order to keep the purge line behind your print). So it seems like Prusa could easily unlock say "235" mm of Y were they to support longer print sheets. Or maybe they plan to put something else in that space back there.
