Can you give more details on what you think could/should be done by
default?

For such a use case, I would compile each gdb with a separate prefix
(e.g. --prefix=/opt/gdb/<version>), which would give each install its
own data directory. So from my point of view, the "feature" is pretty
well-covered.
