One of the most annoying things in #electronics: you can run a trace under a 0603 resistor, but you can't do that under a 0603 capacitor. The IPC footprints are slightly different, taking the height of the capacitor body into account.

afaik jlcpcb screw around with paste apertures to their taste. If it's just about the solder volume / resulting fillet shape there'd be other ways to get good results unless it fails because production files are altered.
