That may not indicate more than these protocols have not received enough attention.  It doesn't prove they are correct, nor does it prove that they are weak.  There is just no evidence.

Going by past history, however, amateurs general design bad algorithms since they repeat known mistakes.  That does not mean this is the case here.
