[Sidefx-houdini-list] ROP asset question

Problem I can find with this approach is that I am writing several python
scripts in the HDA definition. the ROP uses all of this python and I am
wondering if this could ge done easily using a Mantra rop.
I have scripts  for several events, parameters callbacks, etc ...
And I am containing them into the HDA definition. So far I want to make it
self contained becasue is a prototype.
I cant change the Mantra definition so I cant save my scripts into it.
What I am looking for is having a layer on top of the Mantra ROPs that gives
us total control, about the interface, how it integrates with the pipeline,
etc ...
I can see the problem about updating to new versions of the Mantra ROP.  I
am wondering if you have  Mantra ROP for H11, and then in H12 it comes with
new properties,when I open my old scene, or load my asset will it update the
Mantra ROP to the new one with the new properties?
Thanks for your answers, really helpful,
