I was thinking about it but I do not find this part as too significant there,
it is just another illustration.

Unfortunately sourceware tree does not build without makeinfo at all.  This is
a pretty painful dependency on various hosts I build GDB on, I tried once to
make the dependency optional but I do not find it so easy as I thought it is.

IMO it makes better quality of the output for user.  If the feature has been
implemented and it is useful in such case it should be used.  There is no
excuse not doing so.

I can provide alternative less nifty graphical representation keeping the text
even with older texinfos.
