Of course you can re-hide mach_kernel easily enough but there may be other subtle fixes also. Running the Combo can do no harm and can only help.
Generally speaking, running the combo update vs. the regular incremental version only helps anything if one of the files the combo contains replaces a damaged or missing system file that the incremental version doesn't replace. Otherwise, there is no good reason to download (for instance) the 800 MB combo instead of the ~280 MB regular one (or the tiny little <20 MB supplemental update for those already running the earlier 10.8.5 update).
For some users, the time it takes to download the larger combo versions is a significant drawback. For a very few, its jumbo size could even result in a dangerously full hard drive with not enough temporary free space to apply the combo or for the OS to function stably.
All things considered, I think it is most important that users end up with all the fixes for 10.8.5 so they are running build 12F45 (or a later build if & when that becomes available). For some, just using the Terminal command to hide the mach_kernel file should be enough, unless they have other problems the combo update could fix.
