My guess as to the "why" is that there never was the goal for it to be
(or become) a generic "earmv6hf installation image", but something
rather specific to the Raspberry Pi.  I don't think rpi_inst.img boots
out of the box on a Pi 2/3 because it contains a RPI_INSTALL kernel
called kernel.img while you need a RPI2_INSTALL kernel called
kernel7.img on a Pi 2/3.

I sent a patch[1] to port-arm that makes build.sh release also build a
rpi2_img.gz, both when building earmv6hf and earmv7hf (it might need a
bit of manual work to apply to a current tree).  There wasn't much
interest back then, I assumed nobody really cared about installing
that way and I was just the only one crazy enough to do that :).

I suppose it is, but I'm not sure if it's very *relevant* these days.
I guess most people just want to dd an image to a (micro) SD card,
insert it into their board, turn it on and be done with it.  For some
reason I like to avoid resizing file systems after their creation,
that's why I've always liked it.
