Transparent paravirtualization has little value to developers or technology providers but definitely has value for distros and software/system/support providers. Note for example that Vmware's PVI (for x86) has transparent paravirtualization because Vmware (the largest provider in the world of virtualization software) considers it valuable.

I think it is also valuable for binary only device drivers. If we want those drivers for xenolinux, it is a big plus. [ I don't know if there are binary devices drivers for ia64, but there exist at least for ia32].

My opinion: we should NOT give up this feature. The recent VP patches are critical to catching up with Xen/x86 functionality so we have to accept some short term minor regressions for this. I think all other patches (including event channel) should not be accepted if they break transparent paravirtualization.

Too late for event channel ;-)
