They are reasonably compatible from a compilation perspective. That is by
design. However, Debian only compiles against libsystemd-dev and it is not
known whether all packages would compile against libelogind-dev without some
sort of patching in of explicit support. Certainly patching was required for
policykit-1, although those changes have now been accepted upstream.

That is currently the case for libsystemd0/libelogind0 only at runtime. Doing
libelogind-dev provides libsystemd-dev concerns me as I think we might introduce
FTBFS until we know that all source packages will build with either. Given the
number of source packages in Debian, that is a lot of testing. Hence why we
currently follow Debian and only build against libsystemd-dev.

Does that make sense?
