Not deliberate AFAIK.

The intention is to make xl callout to a script whose name is derived
from the initial part of the disk definition (e.g. the drdb part,
similarly for iscsi and so on).

So, the "callout to a script" functionality is already available as part of
the scripts in /etc/xen/scripts/. This includes a call out to
block-drbd (supplied by DRBD package)
block-nbd, block-enbd (supplied as part of xen tree). Cant we just re-use them
or is there some xend specific aspect to those scripts?

IanJ was looking at overhauling disk handling, including that
functionality.
