The plugin system didn't make it easy to add new algorithms to GnuPG
(it's free software - you could always add new algorithms). The
plugin system just made it easy to distribute the plugins separately
Also, keep in mind that OpenPGP never really supported Tiger. There
was no OID specified, and so it was supported in GnuPG with a
nonstandard OID. This means that no other OpenPGP program (unless
they used the same nonstandard implementation) would be able to verify
Tiger signatures from GnuPG.
Back then, Tiger was the largest hash in GnuPG. That is no longer
true. Tiger is a 192-bit hash. Today, GnuPG supports SHA-256,
SHA-384, and SHA-512 - a good bit longer than Tiger.
