You know there's a --disable-docs option, right? :-)

I just updated the IcedTea forest (http://hg.openjdk.java.net/icedtea/jdk7) to b104
(last update was b89 to b101).

$ cat hotspot/make/hotspot_version
...
HS_MAJOR_VER=19
HS_MINOR_VER=0
HS_BUILD_NUMBER=05

For now, IcedTea7 still builds against the earlier b89 changesets.

Do we know if anyone has used the packages?

My experiences of Shark suggest that production use is still very premature.
