Whats up with all these deprecations

[hrstrand]

As a user of Polaris ( in a Shopify app ), I have not followed the development of Polaris, so maybe this question is silly.

But why are all these basic building block components ( Card, SettingsToggle etc ) being deprecated in favour of all users (like me) spaghetti'ing similar components from Polaris primitives?

It strikes me as counterintuitive in several ways - firstly, the unified UX that Shopify seems to promote ( with their Built For Shopify initiative, for instance) is more difficult to implement - having to make sure that the home-grown components match the look they want. Secondly, the developer experience is horrible! Want a settings toggle? Sure, the one you used is deprecated, but here is an example of how you can do it yourself ( +50 lines of code, vs 5 before )

Am I missing something here? Is there a rationale behind this strategy I just dont understand?
