I do connect to VMs and containers all the time, I just don't see a reason not to speed myself up on my own machines because of it. To me, the downside of typing an alias on a machine that doesn't have it once in a while, is much less than having to type everything out or searching my shell history for longer commands every single time. My shell configs are in a dotfiles repo I can clone to new personal/work machines easily, and I have an alias to rsync some key parts to VMs if needed. Containers, I just always assume I don't have access to anything but builtins. I guess if you don't do the majority of your work on a local shell, it may indeed not be worth it.
