How often and for what reasons do programs patch the Quickdraw bottlenecks?
I know printing causes them to be patched, but under what other circumstances
is patching appropriate?

The only example I have seen is that of a program that wants to resize a
PICT but leave line-widths unchanged.

Why else would one want to patch something like LineTo?
