It does apply.
Regardless of the symmetry, your device somehow needs to be fast enough to cope with your downstream, so with 1000 MBit/s. The very low upstream throughput is bad for you as a user, but for the hardware this part is trivial (non-existent, compared to the work it has to do on the downstream side).
Up to ~450-500 MBit/s, yes - ipq806x (Netgear r7800, ZyXEL NBG6817, etc.), beyond that… see So you have 500Mbps-1Gbps fiber and need a router READ THIS FIRST.
mvebu could cope with the wired side, but usually comes with very broken mwlwifi wireless.
There are some devices on the horizon that might do it, mt7622bv+mt7915e (Belkin rt3200/ Linksys E8450) or ipq807x (OpenWrt support still under development, see Adding OpenWrt support for Xiaomi AX3600 (Part 1)).
