It would. However, if you wish to see videos about Docker coming, the preferred way is to use search at the top and search for Docker. Jeffrey mentioned a couple of times in some of his videos that he stores what people search for and takes that into consideration on what to record next. Jeffrey also replied here:

TL;DR if you wish to see screencasts about Docker, just try searching for "docker" using the search engine at the top because whatever you search for is being stored and used when planning new series/lessons.
I have a ton of docker tutorials with laravel here: shippingdocker.com (signing up gets you free stuff to get you started, whether you want to buy the full course or not!)
If you don't want to sign up to get those, you can find the free modules directly here:
