If they do choose to go with a modifier, I hope it's not control, because I hate accidentally zooming the page with the browser's zoom since it breaks nearly every page out there.
A static map may be underwhelming for the tech people but it is better. No need to load the Google plugin so +3s page load, so better search. Plus, if someone wants the map the link around the image can take them to Google Maps and they can then type in directions, see your reviews and bring actual business your way.
Cutting down the bloat helps, sometimes simpler is better.
At the moment I have a project where I am trimming the maps out of the footer of the home page.
The static maps I am putting in place have been saved with srcset images so the pin is in the middle with mobile and off to one side with desktop. mod_pagespeed does the image resizing so that the images a customer sees are always bandwidth friendly. Why have 3s of download (or more) when you can have a 12k image come down the same http2 connection?
