Sure, there is no problem in keeping it around as long as it is used. There were a couple of platforms that had not seen a lot of changes in the past five years but that are still in active use, I just used it as an indication that I should ask about the status. A lot of the other platforms that list only ever had an incomplete port and were abandoned before they were fully supported in upstream kernels.

Ok, makes sense.

Nice!
