Clean OS install or new hardware should both be daily events at even mid sized companies. Because even if it’s once every 2-4 years per developer that still becomes extremely common in aggregate.
I think the tech giants have warped some people's expectations of what a "mid-sized" company is. I work for a mid-sized company where we roll our own ERP system and we probably average about two clean OS installs per year across the entire development team.
