Jump hosts are a well-tested and widely-deployed pattern already that basically do the same thing without the downside of lockout problems from connecting from somewhere new.
I was recently thinking on a way to open up my Jellyfin Media Server, so I can stream music from my personal collection. Jumpbox would easily incur a lot of traffic costs... due to all of the media being very large(many users of jellyfin suggest that). I also would like to allow friends access to my library, without them having to connect to my VPN.
Having had a very bad experience with getting my home network once DDoSed and once hacked - I am at a stage where a reliable third party source, that can tell me what IP to whitelist, is the only reasonable solution I can come up with. (I know it's not a common use case, but it is my use case)
