I did the following tests:
# macOS 10.12.2, GDB 7.10 (since 7.12 crashes on macOS)
- install eclipse-java-neon-2-macosx-cocoa-x86_64.tar.gz (installing cpp-neon-2 did not allow to update CDT)
- install from https://ci.eclipse.org/cdt/job/cdt-9.2/35/artifact/releng/org.eclipse.cdt.repo/target/org.eclipse.cdt.repo.zip
C/C++ Development Tools 9.2.0.201701301723
C/C++ GDB Hardware Debugging 9.2.0.201701301723
- install GNU ARM Eclipse plug-ins from a local folder (IGdbDebugConstants.GDB_PROCESS_CREATION_VALUE)
- start a QEMU debug session, halt in main()
Results (with GDB 7.10):
- the '${cross_prefix}gdb${cross_suffix} (???)' console (new one) reads:

```
- the 'arm-none-eabi-gdb' console (old one) does not exist
- single step, breakpoint, suspend, terminate, restart ok.
- click on the 'arm-none-eabi-gdb' process does nothing.
Problems:
- the new console title is not right, macro substitutions were not performed.
- on Windows, terminating the 7.12 session crashes GDB
- click on the 'arm-none-eabi-gdb' process does nothing, non-consistent with the other processes, which select the corresponding Tab console.
I also did another series of tests with the attribute IGdbDebugConstants.GDB_PROCESS_CREATION_VALUE **not set** for the GDB process.
Except that, on Windows, the GDB process no longer crashed on Terminate, on macOS the console output was split between two tabs:
- the 'arm-none-eabi-gdb' console (old one) reads:

As you said, not setting the attribute is probably not the right way to disable the new console.
