Old version of symbola font as a part of Guix

[Rubije Keal]

Hello Guix Users!

I was looking for Symbola font [0] and found a message from 2017 [1] were it 
was said that "Symbola package can't be a part of Guix due to a really stupid 
license problem".
Indeed, according to the current license [0] this font can't be added to Guix, 
but there's an old version back from 2015 [2] where author said "In lieu of a 
licence; fonts and documents in this site are free for any use;" and in 
symbola.pdf (from zip archive): "Symbola is not a merchandise; it is free for 
any use.".

Does these remarks let us add this older version of that font?
