Description

The new "balanced" reporter looks great. Just giving some feedback that might help people transitioning...

I just upgraded to 1.11.3 and was puzzled by the warning message The summary reporter in tar_make() etc. was deprecated in targets version 1.10.1.91010 (2025-03-31). Use the "balanced", "verbose", or "timestamp" reporter instead.

My puzzlement was because I was using "timestamp_positives" not "summary" - it took me a little bit to get my head around the changes (it's my first day back after surgery - the brain's not necessarily 100% 🙃) and some experimentation to discover that "timestamp" now doesn't report individual skipped targets.

Perhaps "timestamp_positives" could be aliased to "timestamp" to ease transitioning (with a warning about deprecation and noting that it has the same behaviour?). Presumably the same thing would hold with "verbose_positives" wrt "verbose".
I hadn't used other deprecated reporters, but if they could similarly benefit from a more specific message it might help others who land in that "the thing I was doing stopped working, how do I get it doing what I want?" puddle.

I hope you're recovering well.
