I won't say that a working electoral / parliamentary / judicial system, civil engineering, medicine, etc left intact is a bad outcome. It's a much better outcome than a civil war.

With some exceptions, there were no comparable systems in native cultures; those that existed (some definitely did) often were not capable to keep together a country, even if they worked well on tribal level, or were scalable but belligerent by design.

I also don't think that cultural projection, to a degree, is not a bad thing. It happens constantly, and allows for cultural cross-pollination. It is, of course, best done in peaceful ways.
