There are hurd packages for this package so that should also work.

I wouldn't be so quick to assume that sysconf(_SC_OPEN_MAX) does anything
useful on Hurd at runtime.

Plus, I suppose making 65,000 pointless system calls during the startup of
a daemon (not a particularly surprising value for the limit on open file
descriptors) isn't really that big of a deal, but it feels kind of "ugh"
to me.  If every daemon does that, I wonder if it would have a noticable
impact on startup speed.  Probably not, since in Linux system calls are
pretty fast, but that's a large multiplicative factor.

Is there no way of listing open file handles within a process? It seems like there should be a better way. If the kernel knows what file handles exist (and lsof can get the info) then what's stopping a process from accessing that information directly? Maybe it's just not portable enough?
