Indeed. Last night, I thought to myself, let me quickly compile emacs26
before going to bed, and very soon I saw that I was downloading a huge
rust source file! Suddenly, the compilation promised to be much-much
longer than I had expected. :-(

I would be in favor of making svg default off for emacs together with a
note that svg would require rust.

I've just taken a look and librsvg has included rust code since version
2.41.0 from January 2017, so it probably makes sense to just accept that
rust is the new reality for librsvg.
