It seems like the concern is not in trying the feature, but in being unable to remove it if it doesn't pan out. I too am concerned about this case.

To me, the right response to this concern is not to ban implementation but to try and determine how we can guarantee removal/ modification if this doesn't prove to be effective. And to do that it seems like we have to guarantee that we won't have consumers who depend on this feature that we're forced to support.

I agree with Dave Hyatt that perhaps the best way of minimizing risk in these cases is to agree that this will not be enabled in stable releases of browsers until we have enough feedback for the broader community to make more final decisions. Hopefully this will prevent web authors from relying on the feature's availability and yet still allow interested parties to run what tests they need.



CSS variables are a good example. It's very fortunate that this experiment was never shipped, and I was able to collect a lot of great feedback purely from development builds.
