This would sure be applauded by non-English geda users. (I assume, äüöß 
are included in "accents" :-) But even English speaking users may like to 
print an occasional µF on their silk.

From a license point of view, osifont seems the better choice as it is a 
clean "GNU GPL licence version 3 with GPL font exception". 

With hershey the license is a bit non-standard. The license requires a 
redistributor of the font to explicitly acknowledge its origin. The 
license allows the user to convert the font data to any format except for 
the format used by NTIS: 
https://fedoraproject.org/wiki/Licensing:HersheyFontLicense?rd=Licensing/HersheyFontLicense

The second requirement already makes the font non-free in the Debian 
world. Since pcb format includes the whole font as a set of glyphs, each 
and every *.pcb file may be regarded as font redistribution. Strictly 
speaking, a plain drop-in replacement of the default font with Hershey may 
be interpreted as a license violation.  

Consequently, fedora does not mark the font as free in the FSF sense:
	https://fedoraproject.org/wiki/Licensing:Fonts

I for one would welcome osifont as an option in the default install of 
pcb.
