>>I really expect this is a stable version and that i can keep updating the App for a long time.
I completely agree, but in my experience new versions of Studio often introduce new bugs and problems. If you are lucky the bugs persist for a version or two and then go away again, which I guess is why this option to 'roll back' to earlier versions of Studio was introduced (although as you can see, you can only roll back a few versions and in a few weeks, as more new versions are released, the version you have found is working for you will drop off the list). Good idea to raise a support ticket with MS in the hope that this bug is addressed in an upcoming release of Studio (typically there is a new release every week or two).
You will probably want to make sure that if you test on one version and then export/import to a production version, that your production version is published under the same version of Studio as was used for testing.
>>a lot of effort tha should not be wasted, specially when dealing with Work related apps that modify the workflow and become part of the backbone.
Again, completely agree but based on (bitter) personal experience, I would not personally recommend Power Apps for any business critical function. Others here may disagree, and maybe I have just been unlucky with platform bugs and issues, but I have wasted a lot of time and effort investigating bugs/issues which turn out to be platform problems and not issues with my Apps/code.
