Is the splice family of syscalls the only one that tiny has identified
for optional building or can we expect similar treatment for other
syscalls?

Why will many embedded systems not need these syscalls?  You know
exactly what apps they run and you are positive that those apps do
not use splice?

I think starting to compile out system calls is a very slippery
slope we should not begin the journey down.

This changes the forward facing interface to userspace.

I certainly sympathize with this concern, given the importance of software
portability.  However, the tiny-hardware alternative appears ot some sort
of special-purpose embedded OS, which most definitely will suffer from
software compatibility issues.  I guess that the good news is that much
of the tiny hardware that used to be 8 or 16 bits is now 32 bits, which
means that it has at least some chance of running some form of Linux.  ;-)
