Oh, 034 is new to me, but looks like a perfect match. Currently some 
geoinfo is stored in https://www.loc.gov/marc/bibliographic/bd751.html 
and we were considering (ab)using the non-specified subfield $x and $y 
for longitude and latitude.

That's the plan

I guess "upgrading" a useful and working plugin to a Koha core feature 
is easier than trying to implement it in Koha itself.

Thanks for the feedback!
