Future of shouldUnregister

[VictorGosse]

Hello,

First of all, thanks for this library that we are using a lot in our project and that we love.

My question: will shouldUnregister disappear in the future ?

A bit of context:

• Before the last major update we were relying a lot on the fact that true was the default value of shouldUnregister. With v7, the default value has changed to false which introduced a lot of issues in our codebase so we forced it to true everywhere to ease the migration.
• As v7 is now mainly based on the fact that the default value is false, there are some features that we can't use properly as we have shouldUnregister: true in our codebase.
• I read here and there (eg: issue: validating rules in Controller doesn't apply correctly #10390 (comment)) that this option may become deprecated.

If it becomes deprecated, we'll have to update a big part of our codebase and we would like to do it as early as possible to ease the migration.
