Just to be clear: WyndhamRewards program (points) is a program that is used by many different hotel brands, including Wingate, Super 8, Days Inn, Travelodge, Ramdaa, Baymont, Microtel, etc, etc.
But "By Request" does not work at any of those.
"By Request" only works at the Wyndham brand proper, and nowhere else.
So if you're not staying specifically at the Wynhdam brand, but at other WyndhamRewards brands, "By Request" (instant or otherwise) would do you absolutely no good.
(And, btw, Wyndharm rewards has comparatively few Wyndham brand properties. Many of the other brands have way way more locations. Thus I suspect the average WyndhamRewards member stays rarely, some never, at Wyndham brand properties, but mostly/always at one of the other brands, simply due to geographical distribution.)
