Interesting. In Luxembourg at least you can see the clear seasonal variation and also the enforcement of stricter lockdowns pretty much 1:1 in death rates and infection rates, accounting for the ~2-3 week delay in infection intervals.
... the curves look pretty similar to that of many other countries. There was apparently (according to Wikipedia) one between Nov 23rd and Dec 15th but that appears to have made no real difference, in fact, numbers per million were stable during those dates when they had previously been falling.
