No, it doesn't seem like the same issue at all. I used to use Python for most (production) things, between 2003 and 2008. Due to work, I more or less switched over to PHP and Java, and hadn't written any new Python in anger in years until a month ago. Despite all that, doing some simple stuff in Python 3 felt exactly like Python 2 always had. I'm sure that people who use it on the daily will notice and stumble against lots of differences, and porting large codebases is hardly ever fun, but it's fundamentally the same language.
