You literally just replied and we are engaging discussion — empirically the wiki link above has done literally the opposite of what you are saying! At any rate, the intended relevance of the wiki link regarding loss aversion is the following:
When something bad happens to someone, they tend to overestimate how bad it is relative to something experienced as objectively equally good; it is thus important to be aware of such a bias — in addition to using regular old critical thinking.
In this case, critical thinking could look like the following: “although this is a ‘migration’, what do we mean when we say that? and is it really the same thing as py2 to py3?”
I would tentatively propose “no” to the latter question; and would additionally propose that calling this a “migration” is not terribly useful as although it’s not incorrect, it’s insufficiently specific and seems to invite a category error.
In addition to the loss aversion bias mentioned above.
What are you trying to say?
(Not that I disagree with your point, but it’s unclear.)
