I am generally a fan of keeping documentation short (lest it is
skipped or skimmed), but as long as necessary.

In your case I don't think artificially blowing up the section on RISC-V 
to match others would be helpful.  However, given that binutils 2.28 is
so brand new, that I'd definitely mention.

(My proposals/patches yesterday are about removing references to ten
year old versions of binutils from install.texi, quite the other end
of the spectrum.)
