What about changing the name of the ‘hostname’ option?

So you would replace hostname above with eg. ‘expandhost’
host foo
expandhost foo.bar.com

The configuration option expandhost would work just like hostname, but
making foo.bar.com match with the following configuration entries.

As it's a new setting, old config files won't be affected like
MatchHostname if the boolean field is enabled (globally or locally
without realising the semantic change for some later entry).
