It is opinion, but not quite like rolling dice.
With rolling dice, as long as they land on a flat surface, how they got there, really doesn't matter (though I will say, IMO, elaborate dice towers are cool for about 5 minutes - then they get old and take too long).
Here, most of these - yes you can do it, but unless you (the DM) know the pitfalls, you can EASILY get into a situation where players are just not digging it.
You yourself said, "in small doses." New, inexperienced DMs aren't going to know what doses to use. Once you get experienced you can bend/break all sorts of "rules" and ensure things go smoothly, or even better.
