I had to enable the Tethered Network Services anti-feature in F-Droid for CoMaps to show up.

But the Switch was a unique form-factor at the time that did not have direct competition for most of its life. Nintendo essentially created the hybrid handheld console segment. As previously mentioned, there is much more competition this time around, including the much cheaper original Switch.

I just run some simple services, such as Audiobookshelf or Wallabag, behind a reverse proxy. After reading the other comments, it does not look like there would be any benefit for my use case.

Yes, I have always used a reverse proxy which seems to eliminate the need for multiple IP addresses. It seems like having multiple IP addresses just creates additional cost and complexity, but I have seen many VPS providers offer multiple IP addresses, so I was curious if there was a use case that I was not aware of.
