Question about 1ohm amp stability?

This isn't something I'm looking to do, just something I'm curious about. Let's say you have an amp that is NOT considered 1ohm stable. Is there anything bad about still presenting the amp with a 1ohm load assuming you keep the gain fairly low? Like for instance if you kept the gain at a low enough level to result in the amp outputting at 1ohm what it would normally output at 2ohms, are there still problems that could arise simply in virtue of the fact that the amp is running at 1ohm?
