Except it really does not. Donald X goes back on his own design principles all the time. His design philosophy about what he thought was forbidden to make when he made Dark Ages,
10 years ago, does not have to """empirically""" apply today, as you've wrongly stated.
For instance, Donald X said he would never do a "now and later" Throne variant when he tested a weak iteration of it during the making of Seaside. You, yourself, have used this example before to shoot down a fan card idea (I can fetch a quote). It must have been disheartening to see Royal Galley then, oops.
The point is, don't be overly dismissive of so called "tried and true" ideas by Donald X. The man itself can very well go back on these ideas one of these days. His design references should be honoured as much as possible to create something well-put together, but shouldn't be read as biblical statements either.
And while Doctor does not auto-trash Estates, opening with Banish will. It even does something better for you.
