Is data-id="sap-ui-config" been replaced by data-ui5-config?

In the document of v1.0.0
https://www.npmjs.com/package/@ui5/webcomponents/v/1.0.0-rc.2

It suggested to use data-id="sap-ui-config" to config:

<script data-id="sap-ui-config" type="application/json">
{
  "theme": "sap_belize",
  "language": "EN"
}
</script>

And in the latest document, it suggested data-ui5-config
https://sap.github.io/ui5-webcomponents/playground/advanced/configuration/

<script data-ui5-config type="application/json">

I found that both configuration scripts exist in our project, is it safe that I merge config in data-id="sap-ui-config" to data-ui5-config?
There is also SAP UI5 Card in our project, will UI5 use this config or they are totally separated?
