Yes. I seem to recall having a discussion about the from line's exact format being unpredictable, and for that reason (IIRC) mutt quite intentionally did not try to parse it. Too much variation in too many clients, and also the info in it was not interesting. IIRC the date in a From_ line is not interesting because the e-mail should carry the Date header, and the from line's date may indicate nothing especially useful, if it even exists, which is not required.
The reason to parse an mbox From_ line is not that the data is useful; it's not useful. The reason to parse it is to identify it as an mbox From_ line, rather than a message line that starts with "From " but is not escaped with '>'.
