The issues about sky replacement, to me, are the 'ethics' of replacing a sky that is illuminated the same way as the image where it will be used. Or, if you are A) using your own 'skies' or you are B) 'stealing them' from other images, even if the image creator implies that their sky can be used on any picture.
I shoot my own sky pictures. I keep a portfolio of sky photos so I have different pictures for different lighting angles and clouds, etc. I keep shooting sky shots whenever I see an interesting sky that I think I might be able to use in the future. And I own the sky image as well as the 'foreground' shot it will be joined with.
If you use a sky that has the sun at the far right of the image, casting long shadows, your picture needs to have light coming from the same general or specific direction to look the best. The image must look like it is a natural sky and part of the original picture, even if it was not what you shot at the time.
Ansel might have had days or weeks to wait for the perfect lighting, perfect sky/clouds/etc. or the image to match what he saw in his mind. And, the photographers of Nat Geo and other top purchasers of images will spend months on site to get the best possible photo, forgetting the time it took to make the picture. (It looks like the photographer did a great job of investing the time to get the 'ultimate' picture.)
Reality, for almost all of us is that we don't have infinite time to get everything 'perfect'. We often have only a limited amount of time for the pictures we make. (I did take about 1.5 hours at the Yosemite Valley overlook, waiting for the clouds/lighting/shadows/etc. to help give me the picture I knew I wanted to keep. Getting a bird flying in the sky and waterfalls everywhere from early May snow melt were bonuses of the day. - But, I couldn't spend a day or two there without upsetting my wife!)

Once again, it all depends on what the end use of your photos is. Your ‘ethics’ are mot necessarily my ‘ethics’.
And ethics may not really be the right word to use here. It implies that you are discussing things that have importance to large numbers of people. My photos may be important to me and possibly my family but that’s a fairly small group.
