Am I the only one excited about this new exit on the discussion list or is my

You are not the only one. This exit is the result of SHARE requirement
SSMVSE11018 that I authored and submitted in July 2011:
<SSMVSE11018>
Title: Contents Supervisor Exit
Description: An exit is needed that will pass information about the
module just fetched into or about to be removed from virtual storage by
the contents supervisor. The information should include information
available today to CSVINFO/CSVQUERY invokers such as 1) module name, 2)
virtual storage extent list, and 3) information that can help determine
the MVS data set name or z/OS UNIX directory from which the module was
fetched. The CSV exit should also be called for directed LOADs, even
though the information passed by the system might be only a subset of
what is available for other module fetches and there will be no module
DELETE for this case.
Benefit: CSV monitoring is needed by asset management products,
application profilers, debuggers and other similar software programs.
Today, such programs monitor module fetch by intercepting important
system service entry points such as SVC routines. These are completely
unintended interfaces, thus no documentation exists describing how to
insert the intercept, how the intercept code must behave, or how to
handle the situation that arises when more than one product must
intercept the same system service. These system interfaces are very
sensitive and serious system instability can arise from such programming.
Solution:The exit should be able to be dynamically activated by more
than one product running in a z/OS image.
Impact if no solution provided: Software providers will continue to use
unintended (and 'dangerous'!) interfaces to monitor CSV activity.
