Admittedly, the exceptions and _gotcha's_ for this feature are adding up. Let's see if we can nail down the benchmark differences: @pierredup, in your benchmark, was apcu enabled? Icons caching...

@smnandre does #2167 help with this?

Thanks for your work on this new feature!

Is everyone experiencing this issue using docker?

Ok, pretty sure this issue is docker-specific. I don't use this in docker myself so I'll need some help here.

Ok, looks like this is an [asset-mapper thing](https://symfony.com/doc/current/frontend/asset_mapper.html#serving-assets-in-dev-vs-prod) rather than a tailwind-bundle thing. Basically, `public/assets` shouldn't exist in dev to allow for asset mapper's request subscriber to work correctly.

Any other ideas how to achieve? I really think this is an important metric to make available. Maybe a `HydrationLogger` - similar to `CacheLogger`? Maybe a `HydrationEvent`?

Rebased to 3.4 with the hope of continuing this discussion 😄 🙏🏻

> Maybe a HydrationLogger I did not have a clear idea here and honestly, I feel like this would add overhead we don't want.

I'd still like to see this implemented
