For what it's worth, our stats show that it is in use on 3.58% of
signatures received since August.
Do you have enough data to know in how many of those 3.58% the body
wasn't the same length as the l= value ?
Looking at my much smaller archive, it appears that in most cases the
l= matches the body length so ignoring l= would make no practical
difference.
