I don't think this is a problem at all as long as you have the fractional resampler which works well in this case, maybe it is just a matter of documentation

This is true. The buffers are allocated when the flowgraph starts, and buffer size depends on relative rate. So, no luck getting this changed soon.

Sure, you can use a single tap. You will end up with aliasing when you decimate.

I'd call the addition of run time modification of the RR a feature request, not an issue. Either way you can put it on the github issue tracker. No promises until someone looks at how easy it is to change.

My understanding is that "sync decimator" blocks, of which this may be one, cannot have their decimation ratio changed at run-time. It's a scheduler thing.  But my
  impression may be years out of date at this point.
