Is it though, or is it just a scapegoat or a red herring, especially in the case with a wireless medium? That's been my experience with quick claims to bufferbloat, it's usually something else at play. But again ymmv.

There's always something else at play. Bufferbloat hides problems from the systems that can easily solve them. It doesn't cause problems, it makes them worse.

I mean, I did a speed test with t-mobile 5g home internet, download speed was impressive, but so was the difference in ping time during the download vs otherwise.

Sure, wireless is complex, but there were definitely some way too big buffers in the path. Add in some difficulty integrating their box into my network, and it wasn't for me.

Fair enough, I concede with your assessment, my understanding of bufferbloat (which I have to relearn everytime I look at it) is that the telltale sign is ping to any destination that traverses the uplink exhibits higher latency than usual when you're saturating your download. It's just a tricky thing to test given variability of conditions (and what might be deemed as expected operation) which is why I'm usually hesitant and sceptical, and I don't trust those speedtest websites to gauge it properly.

Every speed test I tried that measures latency under load shows a large difference between fq_codel on and off.

This is very much a problem ISPs have to deal with as big pipes feed small pipes.

codel/CAKE also came from that project, no middlebox needed.
