3.2.12 regression in predicate builder

Hi,

I asked this in another thread, but somehow sent it without a subject, so it may have gone unread by those that could answer - apologies.

Just wondering what the current thinking is about this issue:

    3.2.12 More inclusive fix for regression in joins by oggy · Pull Request #9268 · rails/rails · GitHub

Seems to be affecting a number of people - is there anything I can do to help get a fix into the 3.2 branch?

Thanks, George
