Message in POS about commerce Scale Unit since upgrade to v10.0.32 while still on RetailSDK

[RethaLam]

We are still on retailSDK.
I upgraded my cloud hosted development environment to v10.0.32.
Now when I run CloudPOS in Visual Studio to test my custom, I get the following message after POS loaded but before it presents the Sign-in page.

Warning
The version of the Commerce Scale Unit (CSU) that your Store Commerce point of sale app is connecting to is lower than the Store Commerce app version. This configuration is unsupported as it may cause unexpected behavior or reduced functionality.

Why would I get this message when I'm still on RetailSDK? The latter doesn't have a scale unit, the channel DB is still part of the SQL DB in SSMS. Luckily this doesn't happen on the sandbox environments because they as well as production already have cloud scale units. But we have issues with the v10.0.32 package that I downloaded from LCS on the 17th.
I just want to find out if this is by design or a problem with the RetailSDK that came with the new package.
