I completely disagree with you here. The HDD would just be "another SD" filled with games. If the Switch is booted into hekate or the SX OS bootmenu, then docked and then booted into the CFW with applied USB redirection, all to USB installed NSPs would appear and could be selected.THIS. HDD support would defeat the whole system itself. Also, if we keeping it super real, the Switch library is so garbage that no one is thinking about storing games on a 2TB level. The emulations scene in reality is also limited to 2D games, so again, you don't really need to store anything on that level. When DC or GC run at full speed, this may become a priority.
To avoid any damage you would have to turn off the Switch completely until you remove it from the dock.
Then you can boot it in handheld mode just normally into a CFW (or even vanilla Horizon) without USB redirection to have all the games installed to the SD listed on your homescreen which you then can play on the go.
I'd use this to have "couch only" games which are also big, on my USB drive, like GO Vacation for example. Why wasting SD space for such games? I won't play that game alone in my bed.
And to your 2 TB point ... for people who like to have complete rom collections to use in RetroArch (like me ) this becomes a thing as soon as N64, Dreamcast, SEGA Saturn and maybe even Dolphin are working stable on the Switch. We even have a good PSX core now and PSX games are not as small as SNES games obviously.
