Also, I assume this bug will cause problems in any syscall returning ssize_t (e.g. read, write, send).
It could well do that, yes. I suspect I haven't run into it because the programs I help maintain respect SYS_BUFSIZE_MAX in their calls to those other functions.
For now I suppose we could just document the bug as something Gnulib doesn't fix for those functions. If we ever run into this being a real problem, I suppose we could implement Gnulib workarounds though I hope we don't have to because they'd be a real pain due to EINTR, other errno values, programs expecting no partial reads on regular files, etc.
