Also refer to my message, I explained there how this situation may easily be worked around (just making it always write to target when any :redir is issued is enough for plugins to work; finishing redirections to local variables after function finishes will delete stale redirs in all cases that make sense to write from my point of view and even not finishing should be rare enough and not result in much harm: at maximum vim killed by OOM killer or a few MiBs long file). I have never actually seen plugins with the above code though.

Yes. I think so, too.
1. I can use capture() easily than :redir.
let foo = capture(":mes")
redir => foo
Which is the easy to understand?
2. And, the capture() is used for function arguments.
echo remote_expr("GVIM1", "capture(':mes')")
I think function is better than command to use it in Vim script.
3. I think the patch works well(because I tested it).
But to fix redir is no patches, it is too far to use it in my plugins.
