We live in the age of Wireguard (and Nebula and Tailscale etc). Not being home is not an issue for accessing stuff at home in the slightest, no other public service port exposure required either. In the context of someone considering hosting a media server of their own at all in the first place vs just using cloud subscription options, remote access is a pretty minimal lift. Assuming they aren't already doing it actually, if anything I could see a lot of selfhosters doing that first for other reasons before adding video later.
