Does the demise of RTMP mean that g_ip may cease to be able to handle on demand audio?

Hi Andrew :-)

Although currently the flashaac modes are the default for AOD fetches by GiP, tag version 2.92 already supports the downloading of AOD in the form of AppleHLS streams - the flashaac modes use rtmpdump, while the hlsaac modes use ffmpeg (or avconv).

First try:

get_iplayer --type=radio --pid=b05vcz8h --modes=flashaac

and then:
get_iplayer --type=radio --pid=b05vcz8h --modes=hlsaac --force --overwrite

for a comparison... the main drawback being the hlsaac modes take longer to complete...

AppleHLS as a delivery method will be here for quite a while, I guess...
If they switch AOD-RTMP to exclusively AOD-AdobeHDS, then ffmpeg currently lacks support for it, but already other tools exist that support it - one ominous fact is that AdobeHDS supports "Adobe Primetime" DRM encryption, but let's not jinx things yet... As for MPEG-DASH, I currently am not aware of a tool that can download such streams, but it being an open source implementation, I like to be optimistic that one will no doubt crop up in the future...
So, you can put your mind at ease, at least for now...
