Unnecessary enough to be in every Windows version since Windows XP through the current version 10? It helps in some cases. Look it up.
Yes, it exists.
Show me some
verified performance benefit of having the pagefile on a USB connected SD card vs having it on the HDD.
In some edge cases, it may help. A tiny OS drive, that does not have sufficient space for a good pagefile, and small RAM where the pagefile is used a lot.
Here, we have 8GB RAM, and a 1TB OS drive.
There's a lot of things inside Windows that are mostly not needed. Easier to leave it in than to code it out. And some edge cases can use it.
