@react-router/serve not caching assets in /public for 1 hr

[brookslybrand]

I'm using React Router as a...

framework

Reproduction

npx create-react-router@latest -y
cd my-react-router-app
npm run build
npm run start

Open up the network tab and go to localhost:3000. Look at the headers for the favicon

Used Package Manager

npm

Expected Behavior

I expect assets in the public directory (like the favicon) to have a default cache of 1hr: public, max-age=3600

Actual Behavior

Assets in the public directory have a cache control of public, max-age=0

I'm confused because it seems like this line should be setting a cache control. I think this is how it worked with remix-serve

same issue here... everything is set as "public, max-age=0, must-revalidate", doesn't matter if it's in the public folder or public/assets, any way I can set this myself?
