You should make plugins. That way it can be made available
immediately without waiting for a formal release or formal
testing.
"uic" is not intended to be anything realistic. Especially, it
is not intended to gracefully start anything. The purpose of it
is strictly to start a transient analysis when the circuit does
not have a stable operating point, by jamming in all of the
values and using them regardless of whether they make sense or
not. It is a last resort. These circuits may have several
metastable states.
I agree that there is a need for something more believable. In
particular, the ability to specify something that holds it in
one of the metastable states would be useful.
