I work at a shop that viewed MSSQL as a platform just like the OP describes. Of course noone ever pointed that out to me, but as we migrated more and more away and the graybeards became upset about moving logic out of stored procedures into the application... and async tasks out of Agent jobs into an application job server... it dawned on me. Would not recommend this path, but that is probably because I understand deployments and platforms. if they can fix the ergonomics, modernize the process, I could see it working out. I suppose replacing your OS with postgres could have its advantages.
