Is it common for scripts to download multiple gigabytes to /tmp?

I sometimes manually changed the /tmp to be in memory, or used /dev/shm which by default is in memory. Did not run into any problems just yet, but then again it's just a home server.

Not sure about scripts, but I download and store everything I know I'll only need until the next reboot in /tmp and naturally that tends to be quite a lot from time to time. That worked fine for decades, so I'm not sure what's the benefit if storing the contents of /tmp in memory instead.
