I dont know any sum 41, but metallicas guitars have strong content right down to fundamentals and cab thump, below 100Hz. A staple of their rhythm guitar sound is a lot of content in it from 80-150, in fact.
Interaction in bass and low mid frequencies between the kick, bass and guitars is extremely important, and judicious HPFs are part of that, but what youre saying about modern recordings is simply not true.
I know this because my ears tell me so, but I figured proof would be nice, so with the caveat that fourier transforms dont listen to music, picked a couple of songs with guitar only and spectrally analysed them. Not something I've done before, but hey, every days a school day, right?
You said metallica, and you said moder: off the top of my head nothing came to mind that has a lone guitar in their recent years so I picked battery, as I know that does.

Quite probably not even high passed at all. Lots of 80-200hz.
Soilwork, stalemate has a bit of solo guitar

HPF no higher than 100hz, of which there is lots.
Nile, sacrifice unto sebek.

Quite possibly not even HPFd at all, if so then gently and very low.
Nevermore, ambivalent.

HPF ~100hz max. Also, a beautiful textbook illustration of how a HPF really works (they have gradients)
And slipknot have been kind enough to write a song where the main riff starts with guitars first, then introduces the bass, then the kick, then the full band. Didnt bother with the last one. You can see the low end build up and deepen as the bass and kick are added.



Moral of the story: common HPF is a shade higher than I thought in more cases than I expected, guitars have lots of content in 100-300hz, in fact in shear dBFS its the loudest range by far, and I couldnt be bothered trying to track down solo vocals to do the same thing, but I guarantee they arent hpfd at 300hz in anything that doesnt sound like its being sung through a telephone. Dip or cut round there, sure, depending on the singer and mix; I probably do that in every mix, and its probably normal for most mixes in general. But that is not to make that region comparatively weak, its more that it is too comparatively strong in raws to begin with. HPF? Very rarely, more like 150.
Edit: the slipknot track is heretic anthem, btw.
