Mix of WDS and wired ok?

I have meshed 3 Mikrotiks but speed can be slow for a wireless client going through multiple hops. I can quite easily run a wire between 2 of the units but for the third it would require digging a 30m long trench so it has to stay wireless. Is it ok to have a mix of wired and WDS APs? I presume this would work ok and I can just turn WDS off on AP1?

My setup is quite simple. AP2 provides DHCP and internet. All APs are setup with the same wireless SSID and other settings and I just select Dynamic Mesh for WDS.

Current Setup
AP1             AP2            AP3
192.168.1.3     192.168.1.1    192.168.1.2
WDS ON          WDS ON         WDS ON
  <-- wireless -->   <-- wireless -->


Proposed setup
AP1             AP2            AP3
192.168.1.3     192.168.1.1    192.168.1.2
WDS OFF         WDS ON         WDS ON
     <-- wired -->   <-- wireless -->

I tried it out, seems to work fine
