Hmm, what's the use scenario?  I would think that painfully long
gxids would come from some XA manager software, which would be
responsible for committing or canceling them.  Manual override
of that would usually be a bad idea.

In short, there's probably no "designed-in reason", but it's not
clear to me that it's worth the code & maintenance effort to have
tab completion for that.
