Just a question, will this modification require compatibility? Will it force users to upgrade the Estimator component?

[chaosi-zju]

will this modification require compatibility

I don't think it matters. What do you think?

Will it force users to upgrade the Estimator component

I think it's only about the scheduler, and doesn't require upgrading estimator
