Extensionless files are not served by default

Because it's missing an entry in the default IContentTypeProvider
Some files like acme-challenge (used by Let's Encrypt) or Apple application ids, don't use extensions.

I'd like to know if it could be reconsidered.

This acme-challenge spec?

This doesn't look like static content, it looks like a dynamic challenge-response handshake.

Apple app ids look like they're domain name based, or am I missing something?

This is the set of files I personally needed for Let's Encrypt, you'll notice they don't have extensions

Here is the documentation on how to configure Stripe with apple pay id (it's not apple application id, my bad)

I believe many developers would lose some time understanding why it doesn't work, or even not be able to update the app that easily as it needs a new deployment.

I can confirm that there is no other way to serve these file than setting ServeUnknownFileTypes and optionally DefaultContentType. Registering a custom IContentTypeProvider and adding "" or "." won't have any effect. So it's all or nothing in this case.
