Here:

I don't know why this feature isn't mentioned in the current manual,
maybe it was renamed.

Python is a full-fledged programming language, not a language created
for extending other programs.  Do you really think we need networking,
graphics, and GUI in GDB scripts?  That sounds like an awful overhead.

As for familiarity with it, the GDB scripting language we have now is
even less widespread than Lua.
