I agree, by default the staff lines look rather light in LilyPond. 
Perhaps you can make a point if you statistically show that 
hand-engraved scores use to have thicker staff lines in relation to 
other line thicknesses, such as to convince ‘the developers’ that we 
should change the default.
In the meantime, I do think that it should be easier to override staff 
line thickness in a style sheet without changing other line thicknesses. 
And it really makes sense to have a context property ‘lineThickness’ as 
‘master’ line thickness, instead of a grob property 
StaffSymbol.thickness. I’ll submit that as an enhancement request.
