Exactly! I like being able to log in to any server and use vim/vi without any issues.
I've noticed similar pattern with other tools, e.g. git. I've seen coworkers add all kinds off aliases to simplify git commands, and I'm very much against it since I prefer portability.
The portability aspect seems overstated, or perhaps your use cases are just different. I can already log in to any server with my custom configs; Ansible is what configures my user already, so I just have it dump out my configs. If I can access it, it has my configs.
Admittedly, it does get annoying when I'm sudo-ed to another user, but it's vanishingly rare for me that I am both sudo-ed to another user, and doing enough editing that I really want those configs. Usually a sudo-ed vi for me is just updating a couple lines in a config, I don't need a full config for that
How many times does one remote into a server and then spend significant amounts of time editing files? Usually I make small enough edits that I don’t miss my custom keymaps
