Some of the older breweries with a larger presence have stuck to their staples because they have a market and there's no reason for them to slap their loyal customers in the face by running away from those beers. If you have a good product and a market for it then you don't need to get into the running for fad beers or at least not give up your core market for it.
There was that stretch in the late aughts and early teens where there was a new fad that came and went each year. Here one year and dead the next (e.g. imperial everything, saison, saison again, Belgian yeast in everything). Now fads stretch longer and breweries can specialize in those spaces and build a longer term market in it (e.g. mixed fermentations, fruited saisons, murky IPAs, adjunct imperial stouts).
I'm not sure Alesmith completely fits into OP's list. Alesmith still puts out a few beers with solid trade value and many of the beers still trade fairly well in markets where they do not have a footprint. Alesmith is also growing and exporting to new markets so who knows how long that will last.
