Inline org.eclipse.xtext.common.types.shared.jdt38 fragment?

[HannesWell]

The fragment org.eclipse.xtext.common.types.shared.jdt38 currently contains only two classes of which the OriginalEditorSelector.java can be very useful when e.g. opening test results from the JUnit view for a test case that originates in a Xbase based DSL.

Can you tell why this fragment exists and why it's content is not merged into its host?
I see it has some optional UI dependencies, but so does the host.
Was it created because it uses some, back then new, JDT features?
And would it be reasonable and easily possible to merge into the host nowadays?

For background: I spend some time to find out that this fragment is the 'provider' of the functionality I mentioned above and maybe others could be saved from that too.

was available with the jdt version 15 years ago first

The reason was backward compatibility and compile-time dependencies. Meanwhile, the original reason for the fragment's existence is obsolete. It would be appreciated if you could open a PR to merge the functionality into the host plugin.
