Please also consider that we have to test everything that changed following maintenance. If you replace everything then everything has to be tested before roll out, as opposed to a targeted test of one area affected by a single PTF. (Not saying that this is hard for David's product but a concept.)
If I can apply a single PTF to fix a single problem then I can get this tested and rolled out through the sysplexes much faster and easier than a full replacement. In these days of smaller staffing coming up with people to do a full functional test of a product isn't always easy. my 0.02 cents.
