> I worked at a small company that had a policy of putting devs on front-line support in a rotation, both because it was too small to have dedicated support staff and because the owners wanted devs to understand how users interacted with the system better.
In the 2010s Mathworks, the company that makes Matlab, had a policy that everyone started in frontline support. Including developers. (They probably still have this policy, I don't know.)
The shaping isn't necessarily productive, though. My company has a policy wherein a the dev team are on a rota to assist the support team (and by extension clients) with technical queries. The net effect has been to make me hate customers with a passion usually reserved for opposing political regimes and childhood bullies.

It shaped attitudes and cultures quite a bit.
