Only if you really need all combinations of those options. The flip-side is true as well - multiple booleans creates a combinatorial explosion of corner cases that you have to test for. I have definitely been guilty of adding flags to functions that really should have been separate functions, and being bit by permutations that were not tested. Some of which we couldn't even decide what the proper behavior ought to be when we went back to fix the function.

Wouldn't those same combos need to be tested regardless of which interface technique is used? If there are 8 variations then there are 8 variations regardless of the name-centric or flag-centric approach.

Note that sometimes I add an optional boolean parameter to avoid breaking existing method calls. The default of the new optional flag is the original behavior. It's a case being backward compatible versus changing more code in order to fit a revamped interface.
