I'm sorry, in the end we had to keep this restriction because Windows 10 still contains a bug which causes a BSOD when Boxcryptor tries to move a OneDrive on-demand file to the recycle bin. Please note that the bug is within Windows itself and Boxcryptor is only triggering it. We initially thought that this bug has already been fixed by Microsoft, but unfortunately, this has not been the case. If we would allow users to move OneDrive on-demand files to the trash, their computer would crash with a BSOD. As soon as Microsoft fixed the bug, we can remove this restriction in Boxcryptor.
