Host boot should not be necessary to reclaim memory from an application that leaks memory. The process/processes that leak memory just need to exit or be killed for that.

But that's not "routine," that's "as needed." If you have to boot to do something that you need to do, then booting is reasonable. I think the author must have been referring to routine reboots when nothing is actually wrong, or when the solution to the problem can be achieven by other means than shutting everything down.
