Use Domain pointing instead of javascript for custom domains

I would recommend pointing a custom domain to Spreadshirt’s nameservers, instead of the current javascript method.
This would have tremendous benefits for us. Particulary such a method allows the site to be quickly picked up by google ad be eligible for analytics.
The site and products automatically would be SEO friendly.
I tried the javascript method, but could not get a product image when sharing to any social media site, and google does not index the pages, so they do not show up in organic searches.
Also the !x in the url is very wonky and causes SEO problems.
