Those changes are fine. However there are still some usages of "sp", here are some samples:
java-sample/src/main/res/layout/item_dropdown.xml
kotlin-sample/src/main/res/layout/fragment_home.xml
java-sample/src/main/res/layout/item_dropdown.xml
ui/src/main/res/layout/snabble_buy_with_googlepay_button.xml
ui/src/main/res/layout/snabble_buy_with_googlepay_button_no_shadow.xml
ui/src/main/res/layout/snabble_googlepay_button.xml
ui/src/main/res/layout/snabble_googlepay_button_no_shadow.xml
ui/src/main/res/layout/snabble_item_shoppingcart_product.xml
ui/src/main/res/layout/snabble_view_cardinput_sepa.xml

Please verify yourself if those are fine.

There are some TextViews without a textAppearance attribute. you can search them with this handy regex: <TextView((?!textAppearance)[^>])*> (limit it to *.xml files)
This results for me this list to verify:
java-sample/src/main/res/layout/activity_main.xml
java-sample/src/main/res/layout/item_dropdown.xml
kotlin-sample/src/main/res/layout/activity_loading.xml
kotlin-sample/src/main/res/layout/activity_home.xml
kotlin-sample/src/main/res/layout/activity_success.xml

All sample code yes, but why not applying best practices there too?
