It would solve the problem of text-scale-mode being enabled in buffers, 
where I'm getting inaccurate results from `posn-col-row' because of 
that. And by "inaccurate", I mean different from the ones I'd like.

Probably none. Do you have code that calls `posn-col-row', though? Is it 
aware of `posn-col-row' not being affected by text scale? Does it have 
explicit support for text scaling?
