Indeed, but you can also handle that by using two oscillators, one for long- term stability and one for short-term and lock the short-term to the long-term oscillator with a suitable PLL bandwidth. Comes at some additional cost, but then you can optimize each end better rather than compromizing on one crystal oscillator. That ain't a free lunch either. In the end, you should not stare at the numbers, one must recall the intended application and make that work.
