This part is okay, but is this feature available in all builds of GDB?
For example, is the availability of the 'compile' command or being
able to rebuild the program while the GDB session is active necessary
for this to work?

If there are preconditions, we should mention them, so users won't
expect this to work where it isn't supported.

Why aren't the maintenance commands you add called out in NEWS?

This part is okay.
