Ah yes, of course. Sorry, no need to invent a new term.

Just wondering then, when we create a "series of patches" that belong
together, that have some ordering, how do we organize that?

Still only one shelf per WC (*the* shelf)? Grouping them through
naming ("savepoint-1", "savepoint-2" are two shelved patches belonging
to the same series, but "featureA" (which was reverted) is separate
because it doesn't have the same prefix)? Or do we need multiple
shelves with some name too?

Just one more thought: in the namespace of shelved changes, we might
want to reserve "svn:" or some such prefix, for internal use, to give
us possibilities for features built upon the shelving infrastructure.
