>IBM made a change some time ago, such that if a new extent is contiguous 
with the last existing extent of a cluster, it just made the new extent 
part of the existing extent.

For free space, this was in MVS/ESA 3.1.0.e.

For VSAM, this is available with either 1.7 or 1.8.
I cannot remember which.

For all else, not yet.
