   > Speed: not benchmarked as a headline result — the wins come from native 
columns keeping their type-specialized `equal_to`/`append_val` fast paths 
instead of falling back to byte-encoded row comparisons.
   
   I think speed is an important piece of this PR — could we at least run the 
existing benchmarks? IIRC the TPC-H/ClickBench/etc benchmarks don't actually 
include certain data types, such as dictionaries and FixedSizeList, so they may 
not be the best indicator of performance. But they should at least give us a 
ballpark sense of whether this causes a regression.
