No HIE files found with 2.9.0

[pbrisbin]

Just upgraded a project's GHC to 9.8.4, and re-installed weeder (which got 2.9.0), and now it's no longer finding HIE files:

% stack exec weeder -- --version
weeder version 2.9.0
hie version 9084
% stack exec weeder -- --require-hs-files
No HIE files found: check that the directory is correct and that the -fwrite-ide-info compilation flag is set.

They do exist,

% find -name '*.hie' | head
./.stack-work/dist/x86_64-linux-tinfo6/ghc-9.8.4/build/Restyler/CLI.hie

And 2.8.0 still seems to work,

% stack install --copy-compiler-tool weeder-2.8.0
...
% stack exec weeder -- --require-hs-files
% <no output because no weeds>

Did something change about how 2.9.0 finds HIE?
