I'm interested to know what the future of remove development with emacs might look like. I'm a long time emacs user, and use rust, lsp-mode, magit and projectile heavily. The remote experience with tramp just isn't very good. I've had to work around several bugs that lead to hangs, and even though I'm only ~20millis away from my remote machine performance is pretty bad. I believe I've already done everything I can to make it fast (ssh control master, etc.), and I'm still not happy. On the other hand, VSCode (which I'm not familiar with) or IntelliJ make remote development a breeze. I really like how they hide latency, and handle reconnects well. I've also tried terminal emacs on the remote machine, but I just can't deal with the input lag.
It's remarkable how emacs has been able to adapt over the years, and so I'm interested to hear about some ideas to keep emacs relevant for this usecase.
I've been using tramp for remote C++ development for a little over 2 years now and was disappointed with the performance. Especially when it came to things like `git` operations, but general file system operations were noticeably slow.
I've not settled on using a OSC 52 supported terminal + tmux + emacs daemon/emacsclient directly on my remote machine. There were only a few keybinds I needed to work around (such as C-S-/ and C-Backspace). My tmux prefix key is C-t which I never used in emacs anyway. The OSC 52 allows me to copy my emacs or tmux selections into my system clipboard so I'm happy about that. I still use GUI emacs locally for things like org and note taking.
