Shader models for games where I've added or edited them were taken from graphics API intercepts of shaders which is about as "reliable" as it may be besides the official game programmer input.
Games may "fallback" in cases where a request SM isn't supported by the system but this is usually done via a separate renderer using a different graphics API and/or version of thereof in which case these are listed with a comma separation.
And to get this straight - I'm not a fan of spending a weekend to figure out this information for you to order me to remove it today just because your backend person can't do their work or something. If this is absolutely imperative for you then I'll go over my edits and remove it - but not today.
