Keeping it subtle also gives you the option to replace older parts with (slightly?) more modern reliable (perhaps) alternates?
For example, you could upgrade parts of the groupset to a higher-spec version, whilst retaining the overall look and feel of your Gary Fisher, and without "spoiling" the ride - which of course, comes mostly from the frame.
While as you say, restoring a bike to full original spec might be the "holy grail" for some, practically speaking it might be better to sweeten the build with some newer more reliable parts!
Just my thoughts, of course...
