I got a custom bike in 2014, which was the last year for QR (at least from that maker). It hasn't been problematic, once I learned that I needed either Dura Ace internal cam QR or (arguably better) DT-Swiss QR-compatible skewers that you can crank down hard. This is especially important if you have disk brakes. Ideally, the fork drop-out should be forward-facing (like Enve's 1st gen forks).
If you get the bike and can't live with it, you can always replace the fork.
My main gripe at this point is it is hard to find high-end wheels that are still QR-compatible. Chris King, for example, no longer offers it. Some hubs are backward-compatible (or future-compatible) like White Industries or DT Swiss.
