Also very true! My #1 choice of supervisor was pleasantly honest about that. He wasn't tenured, and after we'd met a few times to talk about maybe me starting a program with him in the fall, he told me "I've got bad news. There's a pretty good chance that I'm going to lose my position here due to funding cuts, and that would leave you without a supervisor in 8 months. We're looking at a pretty niche field, and there isn't really anyone else who could take over for the project we're talking about. Sorry, you should look elsewhere."

I still look back and would have loved to do that research, but I appreciate his honesty.
