In my definition a wifi router is a device that routes over wifi-interlinks.
If there is only one wifi-radio that 'routes' do a ethernet cable
connection I would call the device an accesspoint.

You are right that we assemble our systems from off-the-shelf components
nowadays, building them into watertight boxes. We have made antenna's in
the past (such as biquads, cantenna's and waveguides) and built
('invented' if you like) the first wifi-accesspoint for outdoor-use with
power-over-ethernet (some old pictures are here:
http://webfolder.wirelessleiden.nl/Regenpijp%20-%200.01/Desktop-Images/4.jpg
a link-sys ap with homemade biquad antenna in a pvc pipe).
This device was turned in a commercial product by a Dutch startup
(www.wandy.nl) and some years later by companies like Ubiquity and
Microtik. We now use exclusively the Ubiquity devices for the
interlinks, the idea coming full circle ;-)

If you want to built a large, reliable network it makes sense to
standardize the hardware and use off the shelf components.
