Didn't write that Python wasn't available for ARM. What I did write is that the work for porting MacOS to ARM is ongoing, the work to port Python for MacOS on ARM is dependent on Apple's work and building Ren'py for MacOS/ARM is at the end of that chain of dependencies.
I don't know what you're so butt-hurt about...I made an observation that this will make distros bigger - not orders of magnitude but more than you're suggesting - and it ain't up to
Runey to enable this - he's at the end of the build-chain on this.
ADDENDUM: I downloaded the current HH MacOS build for the hell of it and there's about 33MB of system files between the MacOS and the Ren'py folders. Adding MacOS multiarchitecture binary support will, at a minimum, double that but it's more likely that that number will be higher in the first releases of these pieces.
