This

If 1.5.0-SNAPSHOT is in the reactor/local/remote repo it should leave as
is. If this is not the case then you have a bug
It is.

Should never downgrade to older versions, so FAD
Usually I agree with you, but both projects (pom-project-a and
jar-project-b) are under my control. The use case I tried is I don't make
change in pom-project-a and jar-project-b but in release-test. So I want
to release release-test. Because of no change in pom-project-a and
jar-project-b I can "downgrade to older versions". Perhaps Versions Maven
Plugin is not the right tool for my use case.

Update-* should only move forward
Maybe I missunderstand the documentation of the goal because of the flag
-DallowsSnapshot.
Update-parent has a special case where it will try to fix child projects
so
they can be built, a side-effect is that it might downgrade to a real
version... Perhaps that "feature" could be moved to a fix-parent goal
