In what scenarios where custom server is better to Kestrel?

• I am wondering about niche protocol such gemini
• or specific use-cases with existing protocols (ie. performance/stability etc.)
• or specific connection types (socket, file sockets/pipes, etc.)?

I wonder if @Tratcher has some ideas.

In some 1:1 communication with e.g. micro-controllers Kestrel may be overkill. There a custom TCP-server can be a better fit.

When it's 1:n (1 server, n clients), as well as public facing a full-flegded and proven server like Kestrel is -- of course -- more suitable.
