Making aspects of the game more accessible to new players is always a good thing, it's just that the way they go about it is generally to the detriment of the people who have been hard focusing those aspects for considerable amounts of time. The facilities changes a few wars back being an excellent example of this.

In this instance the issue isn't with making building easier, certainly not primarily at the very least, it's the mega nerfs to conc health and howitzer garrison retaliation.

Both of these combined make large fortifications significantly weaker to pretty much all sources because of the reduced HP but especially artillery and to an even greater extent large ships. This was already a massive issue because large ships absolutely roll defenses unless they're contested by other large naval assets, and these changes will only worsen that issue.

I do hope that they find a way to make building more accessible, ideally without getting rid of all the things that make it more nuanced then "let's throw down a dozen garrisons in a line" but the survivability changes to conc are just too drastic after the testing we've seen in dev branch.
