Notably, the tar command in OS X 10.9 (?) and later already supports automatic compression format detection (though we don't use that in MacPorts at this time: we decompress, then pipe the decompressed file to tar).

In case of multiple distfiles you will always specify the full name
anyway. This would be that for an option such as this example:
distfiles foo.tar.gz \
It is fairly obvious how to extract these files. There is usually no
need to specify how these files should be extracted, since most
compression methods can be deduced from the filename.
The command 'use_* yes' would then only set the extract.suffix
accordingly, instead of the explicit extract.cmd. These two options
would then be equivalent:
