Not "most" but certainly many. I love remote dev (via Remote Containers in VSCode) for large C++ codebases (which could not even compile on my Macbook because of different architecture). Running `clangd` LSP on my local machine would be a nightmare (it could easily eat dozens of CPU cores and tens of gb of RAM when indexing), but on remote workstation it is a breeze. Also I could work on multiple branches simultaneously, spinning multiple VMs and running VSCode remotely on them. So basically my Mac is just a typewriter and everything heavy happens on a remote VM — isn't it nice?
I have never tried the remote ssh setup (even though vscodium is my primary editor). I don't know anyone who uses it daily, and I've never heard anyone irl mention doing it. I think you're slightly biased here by your experience, and assume everyone shares it.
Edit: hell, I've wanted to check remote ssh in vscodium now to know what I'm missing, and it looks like they basically contain MS DRM and are only compatible with official vscode. License is also proprietary[1] and makes it impossible to use it with vscodium or other OSS projects. Yikes.
