@brijrajk Thanks.
Then my suggestion is to add a new API `injectPre`, which modifies the
original plan and won't be reverted when whole stage fallback is induced. E.g,:
```scala
injector.injectPre(c =>
BloomFilterMightContainJointRewriteRule(
c.session,
c.caller.isBloomFilterStatFunction()))
```
and
```scala
val rewrittenPlan =
transformPlan("pre", preRules(call), inputPlan)
val suggestedPlan =
transformPlan("transform", transformRules(call), rewrittenPlan)
val finalPlan =
transformPlan(
"fallback",
fallbackPolicies(call).map(_(rewrittenPlan)),
suggestedPlan)
```
What do you think?
