How would you handle progress reporting with this? Something like
'capture one thousand lines of updated percentages and merge them with
a magical pretty printer'? I don't see real gain compared to what we
have now.
Except that now escape sequences cause that thousand lines to be just
one ultimately long line with escapes in the editor.
You can't strip logs out of information and then magically inject it
back without having it somewhere. It just can't work.
