We don't have such a component because:

1. May leak server information to an attacker (depending on the
information, but some people already get nervous at sending the server
version)
2. Everybody wants to see different things, organized in different ways
3. Everybody wants a different format: text, json, xml, etc.

Because of this variability, we never implemented one, but all the
information is available via JMX.

It is fairly simple to write your own Handler that calls
`Server.dump()` and reports that as response content, or query what
you want and format it in the content-type you want.
You can secure it so that it can only be called e.g. from localhost,
or from known addresses, using ConditionalHandler.

There is the concept of "well-known" URI, defined in
https://datatracker.ietf.org/doc/html/rfc8615, but from a cursory
exploration I could not find any standard well-known URI in the IANA
list (https://www.iana.org/assignments/well-known-uris/well-known-uris.xhtml)
that reports some "server status".
