It seems the new thread does not appear, so, after all these posts, one more will not make it worse...
Here is a decription of the several resamplers:
resampler2x_b: same as regular resampler, but resamples to 2x the source sampling rate
resampler2x_c: resamples to 2x the source sampling rate, but the code added to decrease the volume in case of overload was removed
resampler2x_d: same as 2x_b but with a lower volume, to guaranty no overloads
resampler2x_e: same as 2x_c but with a lower volume, to guaranty no overloads
resampler2x_f: same as regular resampler, but resamples to 4x the source sampling rate
resampler2x_g: resamples to 4x the source sampling rate, but the code added to decrease the volume in case of overload was removed
So, leeperry, is strange that at 2x you prefer the 2x_b compared to the 2x_c and then at 4x you prefer the 4x_g to the 4x_f.
What was my idea?
When in a digital signal the maximum available value is reached, we cannot know if we are in the presence of an overload or not. It could simply be the highest value of the signal, or it could also be a value below that. In the first case, there is no problem, no distortion is added, but in the second case, don't.
When we oversample a signal like in the second case, some of the new samples could be outside of the valid range. There, if we disable the code that corrects that by lowering the volume proportionally, the distortion would be higher, and this would affect particularlly the higher frequencies. So, when leeperry first said that he prefered the 2x_b, it was possible that it could be caused by an overload. Later, when he prefered the 4x_g, it showed that cannot be an overload problem (it was a bit strange that in a dialog existed any overload, but who knows?...)
In any case, I have found one more good reason to add the possibility of oversampling to reclock: help to avoid the overloads that could exist in the original signal.

I hope I was clear enough, but I only have learned this in the past two days, so it's all still very new to me...
