Column Expression (Legacy) replacement

I am just jumping on the forum to express my concerns about column expression nodes that are entering “legacy” status now. This essentially assumes that it will be deprecated soon if my understanding is correct.

I am really worried about this, because our company has some major workflows that run hundreds if not thousands of column expressions. What will be able to replace this versatile node? I love to use it and have tried to change to java snippets, sting manipulation, and math formula. None of them work for me.

Does anyone have some advice?
