 I also considered compressing the passwords file, but I couldn't even get
 brotli to give it a decent ratio.

+## RAM use is kinda high
+
+I tried to reduce the thread count in Tokio, but it's still around 12 or 13
+MiB even when the server is doing nothing.
+
+I'll leave in the minimize_ram setting for now, but it doesn't actually
+reduce RAM use.
+
+## Server names can't have spaces
+
+I tried to figure out the percent encoding and it didn't work.
+
+Maybe Base64 would be better or something? At least it's unambiguous and it
+can go straight from UTF-8 to bytes to ASCII-armored.
