Sila Minor Complaints/Feedback/Feature Request

I have two Silas in a mesh configuration. There are some idiosyncrasies with this setup. As soon as you add a Sila to the mesh, the 5ghz low band appears to become reserved for communcation between the routers. I have an ethernet backhaul between the two. It would be nice if there were a way to explicitly configure the network to use the ethernet exclusively, thereby freeing up both 5ghz bands for end devices.
Because I have ethernet between the two Silas, I've intentionally placed them at opposite ends of the house in order to minimize overlap. It seems like they don't really like this configuration, and the secondary router often drops out of the mesh. That's speculation on my part, it could be dropping out for some other reason, but here again it would be nice to eliminate the possibility by forcing exclusive use of ethernet.
Because I'm too clever for my own good (but not really that clever), I tried to work around the above issues by taking them out of mesh, and simply configuring the second Sila in bridge mode. This has the desired effect of forcing ethernet to be used exclusively, but introduces other issues. Specifically, when a wifi device roams from the primary Sila to the secondary, it loses internet connectivity. I'm pretty sure this is happening because the primary Sila is getting its switching confused when the device's MAC migrates from a wifi port to a wired port. Some other routers do have the ability to handle this correctly (fast MAC aging or whatever) and it would be nice if the Sila had this feature as well.
