Anaconda may use it - but I doubt it. It's a lot safer to simply look
for the signature of the partition content to see what it is. It's how
md and lvm is detected, so why not swap and ext2/3/4?

What "format" (presuming you mean mkfs) reads the partition type? I
cannot find anything in man pages or anything that indicates it reads
anything to determine the filesystem type. Ie. how would it access the
partition table if you do "mkfs /dev/sda2"?? The table is on /dev/sda
not 2.

I've not seen it use - not even during installation. It would be
interesting to see an example - so far I've never seen any indication it
uses it, not even during upgrade/installation.

I have a map of the United States.  It's actual size.  I spent last summer
folding it.  People ask me where I live, and I say, "E6".
