It's not something appreciated until you're gone sadly.
My first job out of college was at Cisco. I worked on the software team but all our work was done on hardware in remote labs. So a lot of the job was just getting connected to that hardware in lab.
I wrote a bunch of scripts to automate reservation of hardware, remote power cycle, running tests. It was all initially to make my life easier. Would get asked to share them by other engineers.
Eventually after 4 years I had a complete library written that our entire team was using. I wonder if they're still being used today. I liked writing those scripts and helping other engineers more than my actual job.
If those scripts broke after I left I would assume the entire team probably lossed productivity significantly.
