Yes, I'm working on sharing RLE encoded scanlines across layers. And I intend
to write "aggressively" compressed files by default. GIMP thinks that some
applications might not like them, but this way of compression is described
in the spec and applications that can't cope with it are simply buggy and
should be fixed. It's not like decompressing such images is any more difficult.
No reason to write files that are up to four times bigger than they have to.

The kimgio reader should work with high precision files (haven't tested,
because I have none). But as Qt only supports 8 bit per color, I have to drop
the least significant data bytes. This can easily be changed once Qt is
improved in this regard.
