You are confusing the “important customer” with “other customers”.

EU is the “important customer”, the users of PWA are “other customers”.

Using your example, you would implement tracking for that important customer (and comply 100% to the requirements as Apple did) but because of this additional bloat, the website would load 2 times slower.

After a discussion with your colleagues, you would realize that:

- Most users won’t care about the slow loading (including the important customer)

- Re-architecturing the website to keep the same level of performance while adding the necessary tracking required by the important customer would delay shipping the tracking by 1 year, past the 2 months deadline required by the important customer.

Back to your desk, you start implementing the tracking that will incur a 2x slower load time.
