Hey Basara , not to put too fine of a point on your description - but jQuery 3.0 has been out since June of 2016 - almost 2 years ago.
They are currently up to 3.3.1 which was released Jan 2018.
We discovered all of this when we were working on getting PCI compliance - the ONLY way we could get compliance to certify was to update to 3.3.1. The Storefront works well - embed was not a feature we needed for this site, and the admin side does not had to leave it with the 1. xxx version.
Just FYI
