We publish “minimum hardware requirements”. If your system meets these requirements, then it would be a bug if it doesn’t work. We recently removed the requirement for AES, so, a lot of hardware now can run Clear Linux OS.
If we add new requirements, then we will announce this well ahead of time, for the obvious reason that we would break many existing systems/installs. Note: we have no intentions of ever doing this.
So essentially, that’s about as close as a promise as we can get.
