First of all, did you disable the calculator? This app is an amazing feat of intellect, and should be retained due to its fundamental worth of ingenuity.
As I read down the readme, I kept saying to myself "ok, that's reasonable," right up until I saw the 300GB free space requirement to build the image. Is that really what is needed to build an image for a phone or is this a one-off?
My understanding is that yes Android build requirements are... significant. Given that a gentoo system can self-host in like <10% of that space, I am somewhat mystified how it got here, but yes that's "normal".

RCS really depends on attestation now? What the fuck?
