If it doesn't do anything - if it doesn't matter, then why care?
I mean this quite literally. Is it worth expending any time or energy on changing habits and tooling when it doesn't matter, and will probably never matter?

Because it's confusing.
I've been doing this a long time and didn't actually know that /> is meaningless, and it would explain some
random bugs I've worked around in the past.
I've seen people "fix" stuff by adding a "/>" as that's "better".
Other than that, I don't really care because as you mentioned it doesn't really matter. But the needless churn is a bit annoying at times, so not a bad thing to get the message out that it's a XHTML thing and doesn't matter in HTML.
