I don't know if this is relevant to every system but a word of caution, deletion of the volume snapshot can prove to be problematic when the next update/upgrade is made available to BS. Some systems were unable to install the new available updates over the previous one because the snapshot was removed. Consequently this called for a complete fresh install, if this is the case, to my limited knowledge removing the snapshot is a process one would have to perform again with a fresh install and a waste of time. If a process was found to make the deletion permanent to all updates then it would make sense to the ones that wants it removed.
I have been using BS from the beginning with the first Beta and now to the very latest both Developer and Public and all were installed both USB and updates over previous for testing purposes. All were applied as intended by Apple to enhance the security of the OS and have found no kind of hardship on the system apart from the documented bugs. Please don't misunderstand me, I am certainly not against others experimenting with the application of applying OS X to non Apple components, I am just relaying my personal experience and thoughts, but if removing a particular feature from BS works for you then by all means go for it.
