Oh, I absolutely would – I’m just making a point based on a previous statement earlier in the thread:

Considering games with no DRM can have it added retroactively, that Steam pushes updates I may not want with no option to decline

If the practice is that you need local backups on purchase anyway, then I fail to see the difference between non-DRM games on Steam and those on GOG. It feels like a different goalpost is being used depending on what service is being discussed.
