I saw differential.getrevisioncomments was deprecated. Is there an alternative for it?
You're welcome to make a diff and say, share it as a paste, but we're not in the habit of pulling in workarounds, and generally focus on the longterm solution. T5873 literally touches every application in Phabricator, it's more a container task than anything else. We've been rolling these updates out as we're working in adjacent areas.
We don't have a "Convert Differential to EditEngine" task anywhere, but maybe we should since someone may want to prioritize it or attempt to build it.
