That's not really a limitation for professionals, though.
Built-in component libraries are always going to be incomplete, and literally all of them kinda suck. Professional PCB designers almost always have to either create their own footprints from the datasheet, or get them from someone else who did. Trusting third-party footprints is probably the easiest way to end up with fundamentally broken prototypes which are nothing more than fancy desk decorations - I can unfortunately speak from experience.
The built-in libraries are basically only used for trivial things like resistor footprints, 2.54mm headers, or solder jumpers. KiCad's libraries are more than good enough for that.
Footprints are less of an issue than schematic library. If you need to say tailor-make QFP-48 footprint that might be some work but you will likely reuse it for multiple parts.
Until you find out that a manufacturer decided to use a footprint which looks standard, but uses a custom pin numbering. The schematic symbols are right and so are the KiCad-provided footprints, but they are still not going to work together.
But yeah, a lot of chip footprints are quite standard, or require only small modifications from those standard footprints. I do still have to hand-draw quite a few of them, but that's because my designs are usually quite heavy on relatively obscure peripherals.
