I checked the Makefile, and it builds from separate sources. Yes, it
is in one repository, but s2disk does not depend on s2ram (s2both does).

Anyway... that's really besides a point.

Interested parties can easily fix up the userland parts of uswsusp,
change crypto, add or remove dependencies, move it to other hosting,
or drop it and start again. Kernel interface is flexible enough. If
Chen wants to move the s2disk encryption into kernel, it is his task
to explain why that is neccessary.
