1.5 is no longer maintained officially, just backports by developers 
that still use it -- which may happen down to 0.9 -- but no new features.

Personally I would prefer to go only with one IMS extensions 
integration, based on current development branch (git master). Besides 
the fact that joining forces will make things move forward faster, 
having two directions for same thing (one within very old branch) will 
confuse people a lot. Maybe Jason will consider trying 3.1.x and we can 
try removing his doubts about this version when he has specific 
questions about what he does not trust.

I strongly think this is the best at this moment, there is already 
confusion with duplicated modules coming from kamailio and ser, creating 
a new development branch based on 1.5 will confuse even more. We are 
working to remove duplicated, thus remove confusion, and we should go 
only in this direction if we want to finish it soon.

Now regarding the trust of 3.x, I can say that 3.1.x is far more better 
than 1.5. In 1.x one could barely use tcp or tls, the tm module had some 
potential races which couldn't be handled without a major refurbishment. 
That happened in 3.x - if one search the recent archive, there were 
crashes reported to 1.5 rather than to 3.1.

If one does not like the mix of kamailio and ser modules, then just 
ignore the modules_s/* for a while and you are set. Installing kamailio 
from packages take care of that and only kamailio modules are installed 
(modules/* and modules_k/*). AFAIK, the openimscore developers are 
working also with 3.x so future code from them will just work on latest 
version of our project.

Cheers,
Daniel
