It would surprise me if it were.  In fact, it did surprise me to think it did.

I have never created a file in /etc/apt/sources.list.d myself.
The only file near there I have edited is /etc/apt/sources.list itself.

Then some other action must have done this on my behalf, apparntly not opam.
I installed opam from the proper devuan repository.

So I have to conclude that I just do not know why the corruption happened.

Too bad.

Wild speculation:  Could Debian have just taken over the packages in 
that repository on opensuse, and then devuan got it from Debian?  That 
would be surprising, but it is at least plausible.
