So, in this kind of case, is there any point of even using it?
I just recently lost 250x4 in a RAID5 due to 1 drive failing and the filesystem on another drive getting completly corrupted. I'm still not sure what happened, but the SATA controller went poof and I think heat is to blame (my fault). I'm still at a loss as to what filesystem I should use, but was leaning twords XFS.
Also just googling while writing this message I stumbled upon http://www.mail-archive.com/linux-raid@vger.kernel.org/msg01981.html , mentioning EVMS ( http://evms.sourceforge.net ). In particular it says it supports resizing RAID5, and it looks like you could do mdadm->EVMS(resize)->mdadm. I know nothing about this, has anyone used it before? It's still updated, while raidreconf doesn't appear to be.

As you have said, there are lots of possible types of failure, and
someone who thinks that raid will save them from everything is an idiot.
However, I use raid in conjunction with LVM on my myth box, and I've
been really happy with it. For me, the issue is that the more hard
drives you have, the greater the frequency of failure. As someone who
has seen a lot of dead hard drives, I believe that normal hard drive
failure is my weakest link. Just a few weeks ago I had a disk die, and
raid saved me (and my roommates who use mythtv) a lot of inconvenience.
Of course, I also do backups of important data.
