This a bit akin to one of the worst aspects of Linux prior to systemd.
The project refuses to define a stable device driver ABI, resulting in
many things.  Of particular interest, possibly world historical, is
that that prevents anyone without insanely deep pockets from creating
their own operating system using the Linux device driver set.

Relevant to your point, from release to release when there's an ABI
change, Linux device drivers break.  A *lot*, and many of us have
scars from this.

Every library Alex officially adds to the Chibi Scheme distribution
incurs an additional demand on his time to keep it working.
Especially given Snow, it makes sense for him to limit them.
