At least they're admitting up front that there won't be working Linux ports.
Probably not a good idea. From TFA: "it is illegal to tamper with a boarding card under U.S. law."
Devices that don't officially support SDXC only advertise support up to 32GiB, which is the capacity limit for SDHC. SDXC introduces a few additional features, and removes the arbitrary 32GiB restriction on capacity, but SDHC devices are nevertheless forward-compatible with SDXC cards (and their increased capacity). The only snag is that the device probably doesn't support SDXC's required exFAT filesystem, so the card will need to be reformatted.
Gentoo may well be the last bastion of mandatory text editing. Hopefully they never aim for "elegant" package management, because the current way is great. And so help me, if I can update Qt painlessly, I'm switching to LFS.
It doesn't suck. How many other distros can that be said of?
Expecting the user to know what they're doing doesn't make it inconvenient. My experience with Slack has been that if you know what's going on, it's easier to manage than anything else out there.
Stupidity, like virtue, is its own reward.
