Complexity can always be added later, usually at low cost. Managing complexity is an unaccounted-for ongoing cost that these decisions almost never take into consideration - often because the people making the decision have no long term experience of managing the thing being added.
The cost-to-change of the thing being added is also almost always never accounted for in the decision-making, again because the people making the decision almost never have the experience of the actual work required to remove it from a running system.
Make sure your architecture decision-making checklist includes these two questions:
1) After we add this thing, how much will it cost to maintain on an ongoing basis?
2) What will it cost to remove?
If neither of these things can be accounted for, defer the decision until real-world data can be found.
Go ask in your communities of practice.
