It is, which is why I’ll only give a brief example here. Have a look at 
the first few bars at this: 
https://imslp.org/wiki/File:SIBLEY1802.14023.d867-39087011616572score.pdf

It shows various strategies of placing dynamics and articulations 
overlapping with the staff (without there even being strict necessity 
for some of them). All of these are abundantly common in 19th century 
engraving and enable far more compact layout. The issue can more severe 
in choral music due to lyrics, but in orchestral music there are more 
ledger lines, articulations, slurs &c. exacerbating the need for 
flexibility with dynamic placement.

Modern aesthetics often favour exact alignment, no overlapping and very 
loose spacing at the expense of huge increases in page count. I rarely 
agree…

Best, Simon
