The bazel community has lots of such switches. Basically every 
new behaviour get's introduced with a --preview switch, that will 
turn into a --revert after some time.

For each switch there is a github issue, explaining the change it 
detail. Why it was necessary, what the changed behaviour is, how 
to migrate and the timeline for this particular switch.
