I reported this about a month and a half ago. Same problem with my RT2860 device, and for the past years I've handled it the same way you did: by having the clients rapidly pinging the AP to prevent them from entering power saving mode.
I never got any response indicating that someone is looking into it, or even confirming the bug, so I chalked it down to ral(4) never having had the ability to manage power saving clients and that a mistake simply made its way into the ral(4) man page. I recently opted for getting an athn(4) device instead, which supports power saving clients perfectly fine. The card (or perhaps athn(4)) induces notably higher latency between it and its clients, but at least the clients don't lose connection all the time.
