Holistic essentially means to look at it as a whole. I think looking at the whole game is the only way to figure out if it has use for your table.But, no particular use of it is "holistic". So, while you, in a seat of looking out at the vista of games, may find it makes sense to look that way, that mode is of little use when considering actual use for one table.
Sure. But that means it takes the place of the multi-tool - the thing you use when you don't have your full toolbox at hand.
I might love the spellcasting rules in DCC and want to use them, but if I'm running an intro game for newbies or children (and I don't want their first experience to be a meat grinder) then it might not be the right game for this purpose, because it can be fairly deadly, particularly at low levels.
Sure, if you have an entire toolbox, then the multi tool serves no real purpose. But I've yet to find an individual RPG that is the entire toolbox, so unless you intend to switch systems mid campaign, the multi tool is still extremely useful, and in some cases outright preferable.
