Of course not, but I'd rephrase what the OP said as something more like "it's unrealistic to expect them to go 'hey, guess what, never mind about all that' after a half a year.

I think it's more realistic to expect that they're going to stick with a UI officially called "Liquid Glass" for the next decade, but it's going to go through some serious iterative changes in the next couple of years -- probably much more than it would have were Alan Dye still around.

God only knows how much money they invested into the new GUI engine for all their platforms. It was a super expensive bet.
