Maybe a hot take, but if you're that concerned about cold starts, you probably shouldn't use a service that scales to zero. If your service is really not used that heavily, it's like $5-10/month for an instance that can handle more than your traffic needs 24/7, hell you can even host other similarly unused services on it!

Because attractiveness of Workers/Lambdas/Functions is whole "write simple amount of code and pay pennies to run it." Downside is cold starts, twisting yourself into knots you will do at scale to make them work and vendor lock in.

If you start to say "If you are using this for production, 5-10/month is real cost you need to pay + transactions" Well, now the cost is about to same to deploy fly.io shared CPU container and it does not come with cold starts, vendor lock in and can run as long as you want. Cloudflare knows that so they don't want to introduce that charge or even talk about it.
