I fundamentally disagree with your point of 'a patch should be released as soon a possible'. A patch releases the fix, but by necessity also puts a bright target on the vulnerability it fixes by providing the information on potential exploitable vulnerabilities in the system being patched. From that moment on it is a race between reverse engineering exploit writers and system maintainers to get their work done first. Having coordination and predictable planning where possible allows companies to include security maintenance into the workload, rather than to have to constantly scramble and react to unforeseen and unpredictable wildfires. It is not about 'convenience', it is a component of a mature security process.
