Yes, what I meant was that I was surprised I didn't change executable-find
back when I added locate-file (especially since I had added exec-suffixes
not that long before IIRC).

I could but the intention of using an integer arg wasn't to speed things up
but to more closely match the behavior of call-process and start-process.
