In addition to that, it would also be nice if the "-E discard"

-E discard is the default, according to mkfs.ext4(8)
Not the most clear man page...
On the (Ubuntu) version I have on my desktop, it also says nodiscard
is the default?!
Hmm, and to make things more complicated.
The RELEASE-NOTES that come with the e2fsprogs source say that the
default is what you put in mke2fs.conf

Mke2fs now understands the extended option "discard" and "nodiscard",
and the older option -K is deprecated. The default of whether
discards are enabled by default can be controled by the mke2fs.conf
file.

Still does not explain what behaviour you get when neither discard nor
nodiscard is listed in that file... *sigh*
