Maybe both flags should be diagnostic?  At least FoldStableValues.  It’s nothing a regular customer would turn off on a daily basis but it might be helpful for diagnosing problems.

> @Stable was added in 8 (back in September, 2013) as an experimental feature. Future JSR292 performance improvements rely on it, so it should be turned on by default.
