I'm not aware of very many people who'd be: even back when I used Java,
most people I worked with were not fond of this style at all (and IOC
containers, which were gaining in popularity, tended to promote
constructor injection — where all values are set in the constructor
— more than property injection — where the constructor takes no
argument and all properties are set via setters).

Going through constructors/atomically building objects has issues mostly
in two situations: a language without keyword arguments — which can be
neatly side-stepped by using "builders"; and objects with far too much
configurable state — which should be solved by breaking things into
smaller and more self-contained pieces.

To answer the question, no, I can't say I would be happy.
