Yes, I noticed exactly this earlier (because I'm using the testing repo) :

I first thought about trying to make the debugging output of pacman more
verbose, but then I remembered the python script of stonecrest, so I used
that instead, by lazyness.
So thanks a lot for this patch, I think it's very helpful.

Btw, stonecrest later updated his script, but it still considered makedepends
like depends, which is not exactly what we want from pacman point of view.
So I hacked it in a bad way, and here are the final cycles I found :
