Additional Comments --
Timeline: Got switch Fall 2018. Added 90DNS settings to stock 6.2+ExFAT SysNAND, then entered RCM with a wire between heatsink and pin10. Made full BOOT1/0+RawNAND backups. Followed guides to derive keys and install Atmosphere (Kosmos thru SD-Setup).
Used CFW extensively online with only 90DNS (no Incognito/error log wiping/etc) for protection, including homebrew installer, RetroArch updater, etc. Was online while playing many NSPs which had online play, but they could not connect. Never had a time when 90DNS was not active on Wi-Fi connection. Updated to 8.1+ExFAT with ChoiDujourNX.
July 6th, I used EaseUS to resize my SD Card partition and create an empty hidden Fat32 partition. I then used Hekate+Nyx to make my CFW SysNAND into an EmuMMC. Confirmed it worked by booting thru Nyx. Put RawNAND+Boot1/0 onto clean ExFAT SD, then restored to SysNAND via Hekate. Disabled AutoRCM and launched SysNAND normally. Updated to 8.1 thru System Settings, used RCM Jig and held Vol+ during automatic reboot to return to Hekate and reenable AutoRCM, and confirmed still only 8 fuses burnt. Rebooted to SysNAND via Hekate. Updated all cartidge titles, downloaded some free games thru eShop, confirmed all my friend requests that had piled up, played Fortnite. Still not banned (as of 7/30/19), and will return to update if that ever changes.
Biggest takeaway is probably that for the last 10 months, 90DNS has been safe and sufficient to avoid a ban, as long as you're sensible with wi-fi connections.
EDIT 11/16/2019:
Still not banned. Have really been enjoying Pokemon Shield online! It would tentatively seem that having CFW files on your SD card, having NoGC patch enabled when booting to stock, and booting stock thru Hekate (to prevent fuse burning) are not currently triggering bans.
