I thought the standard required PAD to be usable as random scratch

The standard does not specify multi-tasking.

So I'd expect Gforth to allocate one for each task.

My question is: How have you used PAD?

Gforth
systems aren't likely to suffer memory shortages from doing that.

Depends on the number of tasks.  If PAD is not used in a way that
requires one PAD per task, it's better not to implement that.
