A magic values of 20 is completely empirical.

I suspect a magic value is fine in this context. I do not believe that
"hundreds of concurrent module loads" is a valid real-life load. It
sounds more like a "systemd does horrible things at startup".

20 sounds plenty big enough to me.

But I guess this is one of those "only real life will tell".
