I guess the issue is when you get a 41 patch series, and there's only
one patch you need to look at. There's times I get Cc'd on patch sets
that I have no idea why I'm on the Cc. If I skim the patch set and
don't see a relevance, I simply ignore it.

But there may be one patch I was suppose to review and I miss it. I
personally prefer to get only Cc'd on the cover letter and the patch I
need to review. Now, if that patch is dependent on other patches, then
perhaps it would be nice to be Cc'd on them too.

In other words, I much rather be Cc'd on only the patches that pertain
to me (and the supporting patches for it) then the entire series.
Especially when it's 40 patches or more.

Yes, it's a single click to delete patches that I don't need to look
at, but what I usually do in these cases is just delete the entire
series.

Note, as I do a lot with stack traces, this entire series pertains to
me and I'm happy I was on the full Cc list. But there's other examples
where it does not.

BTW, lore.kernel.org has a way to reply back to the list.
