I believe it's kind of sad that in the days of 2 TB USB sticks that 32kb matter.
That said I don't expect a massive impact from this change, but removing unused code is going in the right direction.
And then on top of each restaurant app, you also have Uber Eats, Door Dash, etc., which again, basically so the same thing.
There should really be a single fast food app, I select my restaurant, and it shows me the options (which is basically google maps with mobile websites that would actually work). There's no reason for every restaurant and delivery service to have their own app.
