Wouldn't it be helpful for civilian towers to do that?

I had a civilian tower say "check wheels down" to me last Saturday.
This was only my second XC to a towered airport, so I had no idea what
they said. I asked my instructor and he told me, so I got a good
chuckle out of it since our gear was (hopefully) fixed - I looked out
the window to make sure it was still there... But, considering a
previous instructor of mine became my ex-instructor after a belly
landing, I guess a little reminder never hurt...
