<p>I will add my perspective here that in the past I've used TIGER
PLACE data to upgrade boundaries in Mississippi and add missing
ones as well. The original TIGER boundaries in OSM may be
outdated, and they sometimes improve them over time, so carefully
looking and comparing them is important.</p>
<p>So I think if you're looking at a dataset and importing a TIGER
PLACE boundary, and you're doing them one by one as needed, that
would be fine.</p>
<p>To add a specific example, a couple months ago I imported the
TIGER/Line 2020 Place Shapefile for the city of Diamondhead,
Mississippi (<a href="https://www.openstreetmap.org/relation/110003">Relation:
Diamondhead (110003) | OpenStreetMap</a>). This is a city
that is fairly new. Previously it was simply a Census Designated
Place, but about 10 years ago the people there officially put in
the effort to get it established as a city government, and the
City's boundary did not match what the original CDP boundary was.
In this case it was an improvement to outdated data, and was
personally checked by me and compared to the previous data. <br/>
