Our in-house parser does consider (...) comments, and my patch does not
change how they are handled: they are still kept after the address part.

However, another piece of code does strip everything behind ">":

sub sanitize_address {
        ...
	# remove garbage after email address
	$recipient =~ s/(.*>).*$/$1/;

introduced in 831a488b76e0 (git-send-email: remove garbage after email
address, 2012-11-22).

IMHO, it's OK to continue doing this: removing comments from To: and Cc:
is not really a problem (and I think we've seen nobody complain about it
since 2012). But after my patch, these two lines can probably safely be
removed, as there can no longer be "garbage" after the email, only
comments.
