looks fine to me :)
(at least, under your specific circumstances...)

That's right.  Nothing to worry about, if only you (or other trusted
users) can make use of the forward proxying functionality. This is
normally the case, when the proxy is behind a properly configured

What you don't want are open proxies accessible to the public. In this
case, you'd need to configure one or the other form of access control,
e.g. IP-based, or via user authentication... (any such configuration
would have to go in a <Directory proxy:*> ... </Directory> directive).

Accidentally misconfigured proxies (intended to be a reverse proxy,
but setup to also act as a forward proxy), as part of a publicly
accessible webserver, is the most typical problem scenario...  but
I don't think that any such concern would apply to what you set up ;)
